Installing CC on different drives - issues

I have two drives installed on my computer, a 250GB SSD (my C: Drive) and a 1TB HDD (my 😧 Drive).

Currently, my OS is installed on the C: Drive, but I have my Program Files installed to the 😧 Drive by default.

When I tried to install Adobe CC (including Photoshop) onto my computer, it doesn't give me the choice to install it onto a separate drive, so it installed onto my default drive (D:), however, when I did this I wasn't able to launch the program properly.

So ok, some programs can't run off the 😧 Drive, I've encountered the problem before, but Adobe CC didn't give me the option of installing it onto a different drive, so I had to change my default drive back to C: (using the Registry Editor program) and install it then. When I did this, I was able to run the Adobe CC apps fine, but all the programs installed on my 😧 Drive wouldn't launch properly. I then switched the default drive back to D:, and all the programs installed on there ran fine, but I couldn't launch Adobe CC properly, even though it was still installed on the C: Drive. It seems like I either have the choice of having Adobe CC, or all of my other programs run properly, but not both for some reason?
So in summary:
Default Drive is 😧 - CC installed on 😧 - CC cannot launch
Default Drive is C: - CC installed on C: - CC can launch, but none of the programs installed on 😧 work
Default Drive is 😧 - CC installed on C: - CC still cannot launch (it effectively acts the same as when it was installed on D:) but all my other programs work
I don't know what to do? I need to use the CC programs but I still need to have all my other programs functioning and I don't have enough space for them all on C: alone.
