Thank you for the fast reply! From the faq I deduced the issue was the 64bit vst .dll wasn't downloaded with the rest of the program (because I had no vstplugin folder in my 64bit program files folder, only the 32bit program files folder had the 32bit .dll) I reinstalled the 64bit version, and it still didn't make the folder- it put the .dll straight into the program files folder. Very odd! I added the entire 64bit program files to cubase 9's vst path (took some time lol) but now it's there and working as far as I can tell!
Again, thank you for the quick response, helped a lot 🙂
