Error creating QueryBuilderForm (CoCreateInstance failed) - Class not registered (Error code=800040154)

Hi All,

I'm getting the above error when opening the "configure source" button in workbench.

Version -

Windows 2008 R2

.net 4.8

I've read a lot about the .net 4.6/4.7 version issues, but we don't appear to have either install, i've searched the KB hotfix in add/remove programs and found nothing.

The main reason this is an issue, is i've just moved the SCRIBEINTERNAL DB to a new SQL server (slowly upgrading all this legacy) and some integrations aren't working, as the old server is still being referenced in the error in the alert log viewer, despite changing and testing the SQL conenction for GP.

Any help appreciated!
