Not raining on anyone's parade here, but I'm not afraid to make comparisons. Sonar and my assorted CW VSTs (and only CW VSTs) still seem to use the registry in ways that my other DAWs/video,etc don't have problems with. I'm a long time user and have 'crafted' (shall we say) structures, libraries, and indexes for RaP,Z3,DP,Z2,etc. Near as I can tell Sonar uses these links along with their CLSID's when locating them. I believe I've got everything 64b, but ...
And I do not want to hijack this thread. There are a lot of things going on in the registry for CW relative to other programs for keeping routine data specific to a certain program (which then attempts to go obsolete asap, say Project5). I haven't seen anything resembling a description, and definitely do NOT want to see such a thing of magical registry. The reg is not localized or relocatable from the C: drv. I worry about re-storing a 3 month old BU to a failed C: SSD and potential conflicts with CW's current records, etc.
Per the OP: Please make it stop. Pretty please?
