Hi all. When in Windows explorer and right clicking on a document or folder
the following popup errors occur:

The first is

Validation failed of C://WINDOWS/SYSTEM32/VSINIST.DLL. You are probably
missing a necesarry root certificate.

My only choice is to hit OK and then the following error comes up:

Validation failed of C://WINDOWS/SYSTEM32/VSDATA.DLL. You are probably
missing a necessary root certificate.

When I click ok on the second error Windows Explorer shuts down.

Any help is greatly appreciated.

Cheers
Georg
