I have just purchased a copy of Windows 8.1 32-bit/64-bit from the MSDNAA program through my University. It came as an .iso file so I burned it to a DVD and installed / registered without any issues. I just found out it's a 32-bit install though, and I'm running a 64-bit laptop (Dell Studio 1555). The exact produce name I purchased is Microsoft Windows 8.1 Professional 32/64-bit (English). Is that just another name for "32-bit version that also works on 64-bit machines"? I have 4GB and I would like to code for 64-bit architectures so not having a 64-bit environment will be a real pain. I didn't see any options to choose the install type (it had Windows 7 64-bit previously but I completely wiped it). Any ideas?
