FRx failed to validate frx system database

Hi...

We have client still on FRx which I have been successful at adding a new client user to their system.  But a new Windows 10 user is giving me problems and now the knowledgebase does not show my problem.  When accessing the program, "failed to validate frx system database..."

I've done the normal.. run as administrator and xp compatibility... ran frxreg67... but error still showing

I'm getting them out of this program as it's quite old and a real relic.  But a quick fix on this would be appreciated so I can get this machine up for a bit.

Thank you...

B
