I am using Vienna Ensemble Pro 5.4.13741 (64bit) in Windows 8.1 64 bit. When WaveShell-VST 9.61_x64.dll is in the vst folder a large number of the waves plugins will not load in VEpro5 saying there is a compatibility problem. When I remove WaveShell-VST 9.6.1_x64.dll from the vstplugin folder and leave only WaveShell-VST 9.3_x64.dll in the vst folder then all of the waves plgins will load except of course the waves plugins assoicated with WaveShell-VST 9.6.1_x64.dll are no longer available.
Thanks,
Dave
