Unable to load DLL 'CRMCore.dll' when installing Update Rollup 7

just do as follows
CRMWatson.dll didn't help, but copy CRMCore.dll from C:\Program Files\Microsoft CRM\Server\bin to C:\WINDOWS. Update Rollup 7 installed properly then. CRMCore.dll in C:\WINDOWS was still the UR6 version. Delete this and then install UR12 perfectly fine with the version in the bin directory...

I guess there was an environment variable that did not get set properly, either during the initial upgrade from CRM 3.0 or a subsequent update rollup. It seems rollup 7 fixed the path.
