I have recently installed LoadRunner 12.5 (build 1096) on WIndows7. Not sure if it's the 32 or 64bit. I don't recall being asked so I suppose it just automatically detected.
When I launch VUGen; record; run an existing script, I get the following error:
System.Object CoCreateInstance(System.Guid ByRef, System.Object, Int32, System.Guid ByRef)
Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG))
Any ideas how to fix it? The solutions I found were for v11x and didn't seem to apply to v12.5.
