To date the FactSage 8.3 Apps and Databases are essentially working as designed but some issues have been reported.

• Windows 11 error message: “Hasp security key not detected” (reported November 22, 2023)
  This error message may appear with a new installation on a computer running under Windows 11. We have updated the dongle driver installation files in the FactSage 8.3 installation package. In order to fix the bug:
  1. Download again the updated FactSage 8.3 package (CD-FactSage83.exe or FactSage83.zip), run Setup-FactSage83.exe and then select option Update existing FactSage installation
     or
     simply download the small file Sentinel83_2023-11-22.zip (approx size 2 KB) and copy and replace 4 *.bat files in the sub-folder Sentinel (typically c:\FactSage83\Sentinel)
  2. Run FactSage 8.3 and click ‘Tools > Sentinel Security Key (dongle) > Express driver installation‘.

This will first remove any old driver files and then install the new ones. The error message should disappear.
