Qo I need to re-install FFXIV:ARR? And does the same CD key work? (I bought mine only. CD key version only.)

Thanks guys!
If you are installing Windows 8 32-bit over Windows 7 Home 32-bit no. If you're installing Windows 8 64-bit over windows 7 home 32bit yes. If you're installing Windows 8 (any version) over Windows 7 Pro/Ultimate, yes.

This has more to do with the location of the files. (32bit windows puts everything in program files, while 64-bit puts 64bit software in program files and 32-bit software in program files (x86)) So it's an extreme mess to upgrade 32-bit to 64-bit versions.

If you have more than 4GB of ram you need the 64bit version and if you have 32GB of ram, you need Windows 7 Pro or Windows 8 (any version) otherwise the upper 16GB will not be used.
