Maybe I can shed a little light on this? I just had to run up Cubase 6.5 for compatibility with an old project that does not run in later versions and none of the ensemble plugins will load at all – they all fail the plugin scan with the same error (see screenshot below) saying
“Import DLL MSVCR120.DLL cannot be loaded”
Here is where it gets weird though. On deleting the VST Blacklist.XML file (found on a PC in C:Users(username)Appdataroamingsteinbergcubase6_64) and relaunching, everything goes through as it ought to.
If there is a blacklist folder or file in the affected DAW, it is well worth deleting this & rescanning…….
