I'm running Sonar 8.5.3 on Windows 10. I have never had a problem until a few days ago when Session Drummer 3, PX percussion Strip, and VX vocal strip all started causing problems during a VST scan. I followed the workaround I found on here, which was to run the Visual C++ Redistributable for Visual Studio 2012 Update 4, but no joy. I did stop the scan errors abut they are still not showing up on my instrument/Audio effects. Does anyone know if an update for Windows has been made in the past few days. I do remember it running something but not sure. Also, does anyone know if running the Microsoft patch above could mess up my system? Thanks.
