Problem: Patch installer says "FlexiSign not found." Solution: You installed Flexi to a non-default drive. Use the "Browse" button in the patch wizard to manually point to the correct folder.
Problem: After patching, the Production Manager shows "License Missing."
Solution: Re-install your USB dongle driver. Navigate to C:\SAi\FlexiSign 8.1v1\Drivers\Sentinel and run setup.exe.
Problem: The patch hangs at 99%.
Solution: A background SAi process is stuck. Press Ctrl+Shift+Esc, kill PM_Manager.exe and FlexiLic.exe, then restart the patch.

No patch is perfect. While Build 1115 resolves major bugs, users have reported minor new behaviors:
FlexiSign 8.1v1 (Build 1115) is a patch release for SAi’s FlexiSIGN & PRINT software, a leading RIP (Raster Image Processor) and design suite for the sign and wide-format printing industry. Build 1115 addresses specific bugs, driver updates, and production stability issues introduced in earlier 8.1v1 builds.
⚠️ Note: This is not a major version upgrade (e.g., to Flexi 10, 12, or 22). It’s a maintenance patch for legacy version 8.1. Added support for Summa S2/T2 cutter firmware 3
