The Secunia Officials response to this is here:
- Please try going to C:\Program Files\Secunia\PSI or C:\Program Files(x86) for 64-bit systems.
- Locate the "psi.exe" file, right-click it, navigate to the compatibility tab, and place a check in the checkbox next to "Turn of advanced text services for this program".
- Run the PSI again. It should now work
