I've been struggling with this issue for a while now. As the title says I am unable to install anything directly into my secondary drive, only the main drive (c drive). This is an issue since my secondary drive has the most amount of space. Even when I install on C drive and move to D and then try to use the app I always get some sort of error. I have tried changing the permissions but It has done nothing, tried running as admin and nothing. So right now I am at a lost and am looking for help, any advice?
