This install does a few strange things.
Even though my registry is set like this:
[HKEY_LOCAL_MACHINE\SOFTWARE\Cakewalk Music Software\VSTPlugins]
"InstallDirectory"="G:\\VST-64\\Cakewalk"
the install does not ask for a location, instead it just creates a new one at:
C:\Program Files\Cakewalk\VstPlugins\
That is for the 64-bit install, the 32-bit goes in the x86 Program files folder.
Before I registered it, I moved the 32-bit and 64-bit plug-ins to my 32-bit and 64-bit plug-in folder manually and then registered it in Live 8 (32-bit) and Live 9 (64-bit) before running it in Sonar.
It also renames your older files to:
PC2ALevelingAmplifier_64.old
