Released on June 25, 2024, LightBurn 1.6.03 is a critical patch update primarily designed to address a bug from version 1.6.01 that caused confusion regarding default layer settings. Key Fixes:
Default Settings: In version 1.6.01, a bug fix unintentionally forced "universal defaults" on users who hadn't set custom ones. Version 1.6.03 automatically disables the "Load default layer settings on new or restart" option for users upgrading from 1.6.00 or earlier to prevent further confusion.
SHX Font Bug: A minor fix was included for issues involving SHX fonts.
MacOS Compatibility: This version remains a vital "legacy" option for Mac users, as it is the final version supporting macOS 10.11 and 10.12. Common Post-Update Issues:
Missing UI Elements: Some users report losing their grid or color bar after updating. This is often solved by going to Window > Reset to Default Layout.
Settings Reset: If your laser settings or camera calibrations disappear, you may need to manually reload your preferences via File > Preferences > Import Preferences. Fixing "Error 1603" During Installation
If you encounter "Error 1603: A fatal error occurred during installation" while trying to install LightBurn, it is a generic Windows Installer (MSI) error rather than a specific bug in the LightBurn code. 1. Check Permissions and Encryption
The Windows Installer uses the SYSTEM account to install software. If this account lacks full control over the installation folder, or if the folder is encrypted, the process will fail.
Fix: Right-click your installation drive, go to Properties > Security, and ensure the "SYSTEM" account has "Full Control". 2. Disable Antivirus and Background Apps
Active antivirus scans can block the installer from accessing required files.
Fix: Temporarily disable your antivirus software and close any open laser-related programs (like other versions of LightBurn or machine controllers) before running the installer. 3. Clean the Temp Directory
A full or corrupted Windows TEMP folder can interfere with the extraction of setup files.
Fix: Use the Windows Disk Cleanup utility or manually delete files in %TEMP% to free up space. 4. Reinstall Visual C++ Redistributables
LightBurn relies on Microsoft Visual C++ packages. If these are corrupted, the 1603 error often appears.
Fix: Uninstall existing "Microsoft Visual C++ 2xxx Redistributables" from your Control Panel and download fresh versions from the official Microsoft Support site.
