I tend to do a lot of research and Proof of Concept (POC) work with all the new features that come up in CRM releases. Recently while spinning up a new Organization for some research work, I came across an error message which read
This took a little longer than I expected to get fixed, but the solution was very simple. The reason why you see this error message is because there might be some DLL (CRM/non-CRM) which you have explicitly installed on the server itself in GAC. In my case, it was the Microsoft.Xrm.Sdk.dll
After uninstalling this assembly from GAC and try to create the new Organization, no errors 🙂
Just thought of sharing this quick tip, might save a lot of research work for a lot of people like me.
