IExpress can run in one of three modes:

1. Extract files and run an installation command. This is an “installer-builder” mode, similar to 7-Zip’s 7zS.sfx module or WinRAR’s SFX “temporary mode”.
2. Extract files only. This prompts a user for a destination directory, similar to 7-Zip’s 7z.sfx or 7zCon.sfx modules.
3. Create compressed files only (ActiveX Installs). A .cab file maker front-end. [I have no idea why it mentions “ActiveX Installs”, but I will find out.]

I am primarily interested in the first mode.

The IExpress output package executable has the same architecture as the version of iexpress.exe you run (ie, x86 or x64). On an x64 machine, by default, that will produce an x64-only IExpress package. When this package is executed on an x86 machine, it will fail, and display a nasty message about the file being incompatible.

You can avoid this by generating an x86 package. Execute the iexpress.exe which is in SySWOW64, eg:

C:\ixptest>%SystemRoot%\SysWOW64\iexpress.exe /n test.sed

Even if your installation requires x64, you can still display a friendlier error message to x86 users during the install process, perhaps in your installation script.

When executing a batch file, be sure to run it using cmd /c explicitly:

If you don’t do this, it will be run via command.com – yes, the 16-bit one! Depending on your system, one of the following will happen:

1. On systems that have a working NTVDM, you’ll really get a 16-bit “DOS” experience.
2. On x64 systems, your batch file will not execute at all. (wextract will say: “Error creating process <Command.com /c C:\Users\...\Temp\IXP000.TMP\file.bat>.”)

If you decide to specify the full path, I suggest you use C:\Windows\System32\cmd.exe /c. If the IExpress package is x86 (as recommended), the call to cmd.exe will be redirected to SysWOW64 on x64 machines.

At the Package Name and Options screen, you are given the option Store files using Long File Name inside Package:

Always select this option! What filesystem are you using nowadays that doesn’t support more that 8.3 filenames?! :-)

iexpress.exe appears to use the location of your SED file for its temporary files. To inspect the intermediate results, I applied a deny ACE to this directory:

C:\>icacls C:\ixptest /deny user:(OI)(DE,DC)
processed file: C:\ixptest
Successfully processed 1 files; Failed processing 0 files

That icacls command explained:

• Replace user with your username.
• The (OI) means object inherit, which indicates that the ACE should apply to files in the same directory.
• The (DE,DC) means delete, delete child, respectively.

When you’re done, use the following command to undo that:

C:\>icacls C:\ixptest /remove:d user

In the investigation below, I use the following SED file, which was auto-generated by IExpress:

%FILE1%=

The setup?.exe files are just copies of Notepad. Note that they have to have different names, despite coming from different source directories – more on this later.

Essentially this extracts the files to a temporary directory, then runs cmd.exe and waits.

Using procmon, one can see exactly the process that IExpress uses. Start Process Monitor, then run IExpress:

C:\ixptest>%SystemRoot%\SysWOW64\iexpress /n test.sed

The result, according to Process Monitor:

1. iexpress.exe creates a file C:\ixptest\~test.DDF with instructions for makecab.exe.
2. iexpress.exe launches makecab.exe /f "C:\ixptest\~test.DDF"
3. makecab.exe reads the DDF file and creates three files: ~test.CAB, ~test_LAYOUT.INF and ~test.RPT.
   • During this process, makecab creates a series of files in %temp%, with names like cab_pid_N and inf_pid_N, where pid is the process ID of makecab, and N is a sequential integer.
   • It also creates some zero-byte files C:\ixptest\CABnnnnn.TMP, eg CAB00356.TMP, where nnnnn is a right-padded number beginning with the process ID of makecab.
4. iexpress.exe reads the RPT file, and deletes the DDF, INF and RPT files (without having examined the INF file).
5. iexpress.exe copies wextract.exe into C:\ixptest\test.exe.
6. iexpress.exe merges test.exe and ~test.CAB into a new, temporary file C:\ixptest\RCX441A.tmp.
   • During this process, it seems some of the executable part (ie the “wextract portions”) of the temp file are modified, possibly to adjust for things like the new executable length.
7. Finally, iexpress.exe renames RCX441A.tmp to C:\ixptest\test.exe, overwriting it. It deletes the ~test.CAB file.

7-Zip has this to say about the generated ~test.CAB file:

C:\ixptest>set path=%path%;C:\Program Files\7-Zip

C:\ixptest>7z l "~test.CAB"

This file is used by makecab.exe. Its directives are documented elsewhere [1][2], so I won’t go into much detail. Suffice it to say that this file generates a ‘plain’ CAB file.

Interestingly, you can see the “shell” of this file in the .text section of iexpress.exe:

.Set CabinetNameTemplate=%s

Note the %s C-style (printf) substitution there.

According to [2] (emphasis in original):

The key feature of MakeCAB is that it takes a set of files and produces a disk layout while at the same time attempting to minimize the number of disks required.

This hearkens back to the days when products were shipped on floppy diskettes. Remember Windows 95 (13 disks), Windows NT 3.1 (22 disks), or Windows 98 (38 disks!)?

Fairly self-explanatory – just a summary report.

7-Zip shows us how wextract.exe was modified when forming test.exe:

Looks like the CAB was actually added as an RCDATA resource named CABINET. Neat!

That’s a somewhat different approach than 7-Zip’s 7zS.sfx, in which one simply gloms the installer config file and 7z archive onto the end of the executable.

Here is what the environment looks like during the execution of the install program:

Microsoft Windows [Version 10.0.9926]

USERDOMAIN_ROAMINGPROFILE=WIN-1F6OEAJ3U9Q
USERNAME=user
USERPROFILE=C:\Users\user
windir=C:\Windows
__COMPAT_LAYER=ElevateCreateProcess WRPMitigation

The current directory is C:\Users\user\AppData\Local\Temp\IXP000.TMP.

Note that the cmd.exe is actually the x86 (32-bit) one, since the x86 version of IExpress generated an x86 executable. If you really need an x64 cmd.exe, you can run %SystemRoot%\Sysnative\cmd.exe from your x86 cmd.

A question that gets asked a lot is, “How can I prevent the IExpress temporary files from being deleted?” or “How can I extract the files to a specific [predetermined] location?”

The problem is that the extracted files from a “type 1” installer package get cleaned up after the install program is finished, and the “type 2” installer prompts the user for the extraction location. My answer on Stack Overflow is a fairly complete response to this.

Essentially, you should create a installer-type package, and include in it a script of some sort (eg, a batch file) that copies the files from the temporary location (eg %temp%\IXP000.TMP) to a more permanent location of your choosing, perhaps something like:

@echo off
xcopy /y * "%ProgramFiles%\MyProgram\"
del /f "%ProgramFiles%\MyProgram\copyfiles.bat"

“Can IExpress-generated cabinets contain subdirectories?” or “How can I preserve my folder structure?”

The short answer is: no. To understand this, it’s useful to know how the CAB file within the package is generated.

As seen above, IExpress generates a DDF file (based on your SED file) which contains a series of directives followed by a list of full pathnames of files to include. But no matter the source location, the files are all placed into the ‘root’ of the CAB file^*, as no destination directives were specified. This also creates a requirement that all files be named uniquely (irrespective of their source location).

If we could somehow intercept the DDF file and modify it before makecab.exe ran, we could add subdirectories by adding new directives. The end of the DDF file could look something like:

[...snip...]
.Set InfFileHeader1=[SourceDisksFiles]
.Set InfFileLineFormat=*file*=*cab#*,,*size*,*csum*
.Set DestinationDir=foo
"C:\ixptest\foo\setup1.exe"
.Set DestinationDir=bar
"C:\ixptest\bar\setup2.exe"

If we run makecab.exe directly on a file like this, we can see the paths in the generated CAB file:

C:\ixptest>7z l "~test.CAB" | find "A"
Listing archive: ~test.CAB
Path = ~test.CAB
   Date      Time    Attr         Size   Compressed  Name
2015-01-20 04:52:54 ....A       215040               foo\setup1.exe
2015-01-20 04:52:54 ....A       215040               bar\setup2.exe

But I don’t really see a convenient way of modifying the DDF file, as it exists for only a few seconds.

You could use the same method as described in Persisting files above: in your install script, move the files to their appropriate subdirectories. Obviously this would get increasingly tedious as the number of files increases.

[* CAB files don’t really have “directories”, per se, but are nevertheless supported by several utilities, including 7-Zip.]

If the files you’re including are already compressed, you might not want to compress them within the CAB archive. To do that, add Compress=0 to your SED file, anywhere in the [Options] section:

[Options]
Compress=0

You can use 7-Zip to check whether it’s compressed. For a ‘typical’ IExpress file, the Method will be LZX:

C:\ixptest>7z l test.exe
[...]
Path = .rsrc\RCDATA\CABINET
Type = Cab
Method = LZX
Blocks = 1
Volumes = 1
[...]

Whereas for an uncompressed CAB, the Method will be None:

C:\ixptest>7z l test.exe
[...]
Path = .rsrc\RCDATA\CABINET
Type = Cab
Method = None
Blocks = 1
Volumes = 1
[...]

[ This SED option causes the Compress directive to be changed in the DDF file to: .Set Compress=0 ]

As the generated package is based on wextract.exe, the Details pane will look something like this:

You can override some of those fields using a custom definition in your SED file. You need to define the VersionInfo option in the [Options] section, then add the new section.

Here is an example that takes the data from notepad.exe:

[Options]
VersionInfo=VersionSection
[VersionSection]
FromFile=C:\Windows\notepad.exe

You can further customize that with additional [VersionSection] options. According to a quick dump of iexpress.exe, the available fields are:

CompanyName
InternalName
OriginalFilename
ProductName
ProductVersion
FileVersion
FileDescription
LegalCopyright

An example:

[Options]
VersionInfo=VersionSection
[VersionSection]
FromFile=C:\Windows\notepad.exe
LegalCopyright=© Fabrikam, Inc. All rights reserved.

Which will look something like:

Ta-da!

Note that this only updates the string version information, not the binary version information. See my answer on Stack Overflow for more details.

It’s been reported that IExpress has “security vulnerabilities”, eg:

• Stefan Kanthak – “privilege escalation for dummies”
• Stefan Kanthak – “yet another (trivial) UAC bypass resp. privilege escalation”

However I’m rather inclined to agree with the (unnamed) Microsoft representative who said:

“I still do not see any security vulnerability here. I can see an escalation of UAC privileges, but as has been documented on numerous occasions, UAC is not considered to be a security boundary, so such an escalation is not considered to be a security vulnerability.”

In any case, let us examine these claims to see how they came about.

Myray Irys Software !exclusive! Download Better May 2026

Once, in a bustling dental practice where clarity was the difference between a routine procedure and a complex challenge,

found himself struggling with fragmented imaging systems. His 2D scans were separate from his 3D data, and communicating treatment plans to patients felt like translating a foreign language without a dictionary.

Everything changed when he decided to upgrade his diagnostic toolkit with the MyRay iRYS software. The Transformation

The moment the iRYS software installation was complete, the clinic’s workflow entered a new era of "better." No longer did Dr. Aris have to jump between different programs. The Multi-Desktop system allowed him to browse 2D and 3D views simultaneously with realistic rendering.

One morning, a patient arrived with multiple amalgam restorations that typically caused "noise" in standard scans. Dr. Aris used the 3D SMART (Streak Metal Artifacts Reduction Technology) feature, which automatically cleared the artifacts, making the volumetric images usable and precise. For his panoramic views, the 2D PiE (Panoramic Image Enhancer) filters sharpened every detail, from the dentition to the bone quality. Precision Planning

Planning for a complex implant became a matter of minutes rather than hours. Using the preloaded implant libraries, Dr. Aris simulated the positioning with a few clicks, adjusting for the patient's specific bone morphology. He even used the software to calculate Airway Volumes, identifying a potential sleep apnea issue the patient hadn't even realized they had. Connected Care

The "better" didn't stop at the desktop. During the consultation, Dr. Aris picked up his tablet and used the iRYS Viewer for iPad. He showed the patient the realistic 3D renderings of their own jaw, explaining the procedure in a way that was finally visual and easy to understand. Before the patient even left the chair, Dr. Aris had exported a comprehensive diagnostic report as a PDF to share with them.

By choosing to download and integrate iRYS, the practice didn't just get new software—they gained a "Ray of Solutions" that simplified every stage of the diagnostic process, from acquisition to patient education. Dental Radiography Software iRYS - MyRay

1. Driver Compatibility is Key

The most common issue is the USB Driver.

• The Problem: Windows 10 and 11 sometimes block the specific drivers required by the Irys sensor cradle.
• The Fix: During installation, if Windows asks for permission to install a device driver, click "Install" or "Trust". If the sensor is not recognized, you may need to install the MyRay Driver Pack specifically, which is usually available in the same download folder as the main software.

7. If You Need a "Better" Version Than What You Have

• Check for updates inside Irys: Help → Check for Updates (only works on licensed versions).
• Contact support – if you have a valid maintenance plan, they will email you the latest build directly.

Official Channels Only

The only safe source is MyRay’s official portal (now under Cefla Dental Group, as MyRay was acquired). Follow these steps:

1. Go to the official Cefla Dental / MyRay support page.
2. Navigate to Downloads → Software → Irys.
3. Register or log in (you typically need your sensor serial number).
4. Download the latest Irys Setup executable (e.g., Irys_Setup_vX.X.X.exe).

Warning: Avoid “cracked” or “free” versions from torrent sites. They often contain disabled USB drivers, leading to the dreaded “Sensor not found” error.

UAC Installer Detection attempts to detect whether an application that isn’t UAC-aware needs elevation.

Having neither the time nor the interest to examine old versions of IExpress (say, anything older than the version bundled with Windows 7), I can’t say what the behaviour of ‘old’ wextract.exe is with regards to UAC.

However, I can see that relatively recent wextract.exe contains a manifest with the following:

  <trustInfo xmlns="urn:schemas-microsoft-com:asm.v3">
    <security>
      <requestedPrivileges>
        <requestedExecutionLevel
          level="asInvoker"
          uiAccess="false"/>
      </requestedPrivileges>
    </security>
  </trustInfo>

According to MSDN, asInvoker means: The application will run with the same permissions as the process that started it. In other words, no UAC elevation will be requested for IExpress-generated packages (by default). Of course, the executable inside the package might itself request elevation.

Now that I’ve explored the two mechanisms in play, I’ll summarize the vulnerability mentioned by Kanthak:

1. Download or create an IExpress package which triggers UAC’s Installer Detection.
   • Probably this requires an old version of IExpress, as new versions of wextract.exe seem to have a manifest that would prevent this.
   • One such file that exists already is CAPICOM-KB931906-v2102.exe. The wextract.exe for that file has a date of 2004-08-03 23:01:37, and an OS Version of 5.1 (ie, Windows XP/2003).
2. Place an executable in the same directory as the IExpress package, and give it the same name as its install program (msiexec.exe in this case).
   • The author supplies a very handy program called sentinel.exe for this purpose (just rename it to, eg, msiexec.exe).
3. Execute the IExpress package. UAC prompts for elevation based on the details of the IExpress package itself; but when you elevate, the ‘fake’ msiexec.exe executes from the same directory, rather than from System32. And it is executing with elevated privileges.

Of course, the user still had to consent to the UAC elevation, so it’s not a ‘bypass’, strictly speaking. Essentially it’s unexpected behaviour – you’re ‘piggybacking’ off of a UAC elevation for a different program.

If you’re concerned that someone might try to hijack your IExpress package for nefarious purposes, you can either:

• Specify the install program to be an executable that you bundled in your install package; or
• Specify the install program by full path to the executable.

Obviously the latter is difficult if you want to maintain good compatibility (eg, Windows not being installed in C:\Windows).
