I struggled to find success at first on Win 10, but eventually got everything working. My stumbling blocks on Windows were:
- Getting the correct root VCV folder for projectM.dll. At first I used the parent folder of the Plugins, Selections, Patches, etc. (under Documents). It took a while before I realized I needed the c:\Program Files\VCV\Rack2Pro folder
- I initially installed the wrong version of glew32.dll in \Windows\System32. I started with glew-2.2.0\bin\Release\Win32\glew32.dll and it did not work. All was good when I used glew-2.2.0\bin\Release\x64\glew32.dll instead.
