I, last night, open a "32 bit" project I have been trying to get to open without plugin drama in 64 bit sonar. Drama argely due to the unknowingly irresponsible use of dx effects in 32 bit land.
That aside, I was now greeted with a plethora of CLSID "choices" presumably due to the installation / uninstallation / reinstallation, reset and rescan things I had done of late. I thought of this thread and how, oh no, I'll guess n' choose the last of 3 possible CLSIDs for so 20 odd plugs and save but that won't fix it.
Well I finished my CLSID choosing chores and saved the file.
You know it open then with no errors? - Its a miracle!
