There are variety of ways to end up needing the above, but the primary one is being a victim of Microsoft’s Home Use Program (HUP), which may not provide links to 64-bit Office Professional Plus 2013 (hereafter referred to as Office) in order confirmation emails. And if for some reason you don’t have access to your program code or the email you used for HUP, there’s no way to log in to your HUP account to download a different build anyway. Fortunately there’s a workaround for that:
- If you’ve already installed 32-bit Office, uninstall it
- Reboot the PC
- Download 64-bit Office from the TechNet Evaluation Center (you may need to change the downloaded file’s extension from .img to .zip if Windows fails to mount it)
- Install Office from the downloaded file
- Launch any Office 2013 app
- Activate 64-bit Office using the same product key you were given for 32-bit Office (e.g. the one in your HUP order confirmation email) when prompted
The above method also works for Microsoft Project Professional 2013. All your settings, user accounts, etc. should carry over from 32-bit to 64-bit.
