I have ran through the registry and manually removed all entry’s pertaining to sonar and cakewalk.
I have turned off UAC
I have tried putting the failing DLL's in the syswow and system 32 directories as someone suggested.
I have tried manually attempting to register the DLL's with Administrator CMD Prompt.
I am running windows 7 64 bit verified.
I have tried setting up a new administrator's account and retried the install.
All of which have failed.. The one thing I can't figure out is that I had Sonar 64bit Producer 8.5 installed on the machine previously to installing this upgrade X2.
And the 32 bit version installs the same shared folder DLL's no problem. I'm still hoping someone smarter than me can figure this out. Is this a challenge why yes it is.
