SQL Server 2008 R2 custom extensions or assemblies error

Hey everyone,

We realized that our Live server was running on SSMS 2008 instead of 2008 R2. We were thinking this would be an easy upgrade but it is turning into quite the challenge!

We are running into an error that says "Custom extensions or assemblies were detected on the report server".

We've found a few suggestions on what to do with the custom extensions but the problem is we can't find any of them. We recently had a shake up in our IT and DBA staffing so we aren't sure what we are looking for or where to find them.

Very frustrating! Did anyone else have similar issues? If so, do you have any suggestions for where we can start looking?

Thanks!
