"The version of this file is not compatible with the version of Windows you're running. Check your computer's system information to see whether you need an x86 (32-bit) or x64 (64-bit) version of the program, and then contact the software publisher."
tl;dr Install key does not work.
EDIT: Nevermind, got the proper file via the e-mail. However, for whatever reason, your purchasing site prompts for the download of an exe file instead of an mjr, which leads to the error above. Unwittingly, I wasted one of my restores trying to fix it, but I'm not worried as long as I don't need to restore the program too many times in the near future. Thank you.
