I’ll create a concise feature description and implementation plan for an installer/installation feature for FlexiSign Pro 8.1 (v1). Assumptions: target OS = Windows 10/11, installer should handle fresh install, upgrade, license activation, optional components (drivers, fonts), and silent/unattended modes. If you see a blank white screen on launch:
The installer will copy files from CD 1, then prompt you for CD 2 (Contents and Clipart) and CD 3 (Drivers and Templates).
💡 Tip: If your CDs are scratched, copy all three CD contents to a single folder on your hard drive (e.g.,
C:\Flexi81_Setup), and point the installer to that folder when prompted.
Here are the top 5 issues users face and how to resolve them:
| Error Message | Cause | Solution |
|---------------|-------|----------|
| "Setup has detected that a previous version requires reboot" | Incomplete prior uninstall | Delete registry keys under HKLM\SOFTWARE\WOW6432Node\SAi and reboot. |
| "Dongle not found (Error 7)" | Sentinel driver not loaded | Reinstall driver from CD. On Win10, boot into Disable Driver Signature Enforcement mode. |
| "FlexiSIGN.exe has stopped working" | Compatibility issue | Apply Windows XP SP3 compat + Admin rights. Set system date to 2015. |
| "Cannot find SAi License Manager" | Corrupt license service | Run LicenseManager.exe from install folder -> Repair. |
| "Production Manager won't open" | Conflict with modern printers | Right-click Production Manager shortcut -> Run as admin. |
Provide a reliable, user-friendly installer that supports GUI and silent installs, detects/handles upgrades, manages dependencies (drivers, fonts, plugins), performs license activation, and verifies install integrity.
