Limitations & Risks

Some corporate machines may block execution from removable media.
Bundled JRE increases package size (~40–100 MB depending on minimal build).
macOS Gatekeeper or Linux permissions may require user intervention.
Performance may be slower running from USB 2.0 drives.
File locking or multi-user collaboration features dependent on networked storage behave as usual; concurrent edits risk conflicts.

Troubleshooting Common Issues

While ProjectLibre Portable is robust, users occasionally face hiccups.

Issue 1: "Java Not Found" Error

Cause: ProjectLibre requires Java (JRE) to run. The host computer doesn't have it.
Solution: You cannot embed Java in the portable folder easily. You must either:
- Ask the admin to install Java, OR
- Use a "Java Portable" solution (available on PortableApps.com) launched alongside ProjectLibre.

Issue 2: USB Drive is Slow

Cause: ProjectLibre loads resources into memory. Old USB 2.0 drives are slow.
Solution: Use a USB 3.0 or USB-C SSD drive. Minimum speed: 100 MB/s read.

Issue 3: Cannot Open Password-Protected MPP files

Cause: ProjectLibre open-source encryption library does not support Microsoft’s proprietary password encryption for open passwords (it supports write-reservation passwords).
Solution: Ask the file creator to remove the open password or save as XML.

Issue 4: Fonts Look "Wrong" on Linux

Cause: Missing Windows fonts.
Solution: Install msttcorefonts on the Linux host, or run ProjectLibre Portable via a Windows Portable emulator (like Wine Portable).
