I do use Melodyne Studio, although it's many years since I first installed it and many months since my last update.

I would like to know what the exact error message is. Windows blocks most attempts of users to choose to install into either Program Files folder. It has its own preferred default folder. So, I don't think it goes in that folder you are trying to use. For one thing, that's a 32-bit apps folder. In this, my backup computer, it is in C:/ProgramFiles/Celemony
