[Update] - The shoe maker's elves must be dabbling in DAWs because everything seems to be working just fine now. No magic steps required before opening and running a project. No crashes or VST Scan hangs. The two changes on this system:
1. Installed 2016.12 Sonar update (since rolling back to previous versions or anything else did not solve the problem.)
2. Updated Win10 (Pro) OS Build to 10586.713
- Note: I have -not- installed the latest versions noted in the Early Access sticky on CA2A and Z3TA+2. It's running fine with the previous versions which appears to be the case for most users.
