Hello there.
I apologise for perhaps old and solved issue but I didn't find the clear answer of similar thread =(
I installed x64 virus Ti suite on my Windows x64, I chose VST2, VST3 and both 32 and 64bit plugins, chose the specific directory for VST and I found there only Virus Ti.dll and Virus Ti snow.dll
Any DAW accepted these files as 32bit VSTi, but where is 64bit VST version?
Thanx for any advices!
