Would the bug mean that all of a sudden the scanner doesnt scan the paths that are in the preferences window ? That is what happens. when I scanned the vst plugins All at once I didnt get the vst3 folder or plugins. That was the whole story.
Its easy to check - if you are running the 64 bit version of SONAR and launch plugin manager, the title bar should say Cakewalk Plugin Manager X64
If it doesn't its running the 32 bit plugin manager and if you scan from there its actually scanning the 32 bit path not the 64 bit path - therefore the 64 bit SONAR wont see any results of that scan. The 32 bit and 64 bit scans are stored independently in the registry.
Anyway that issue has been fixed. As I said earlier there is absolutely no reason to use the plugin manager to scan. Just use the scan button from SONAR.
