Unfortunately the clean install deleting registry keys didn't help at all. VST scan crashes on Vsampler and under preferences VST settings the check boxes for scan failed pluggins and scan existing pluggins are greyed out. Even though Vsampler has been uninstalled. It apparently is only looking in the registry and not what's actually on the C drive. Vsampler also shows up in pluggin manager as an excluded pluggin.
Here are the registry keys below I'd think would get rid of the problem. Note also that even though I manually deleted Vsampler.dll from cakewalk/vstplugins, it still shows up in the registry.
HKEY_CURRENT_USER\Software\Cakewalk Music Software\ExcludedPlugIns
HKEY_CURRENT_USER\Software\Cakewalk Music Software\SONAR Producer\Cakewalk VST X64\Inventory\c:/program files (x86)/cakewalk/vstplugins/VSampler3.dll
HKEY_CURRENT_USER\Software\FX-MAX\BitBridge\VoLEffect\c:\program files (x86)\cakewalk\vstplugins\VSampler3.dll
HKEY_USERS\S-1-5-21-3235901495-1408207914-819435497-1004\Software\FX-MAX\BitBridge\VoLEffect\c:\program files (x86)\cakewalk\vstplugins\VSampler3.dll
It seems to me that I need some guidance on what keys are safe to delete in the registry or how I can uninstall VST scan and then reinstall it. I really don't think reset is working correctly. IN the past I noticed several popup boxes that came up during the reset procedure, none of those happen now.
