Upgrade windows 8.1 to 8.1 enterprise

Question

I'm trying to upgrade windows 8.1 to 8.1 enterprise with a product key from MSDN but it says my key is not valid when I use the "Add feature to windows" utility.

This key won't work. Check it and try again, or try a different key

Then I tried with the .ISO but I don't have the option the keep the installed apps. I have only the option to keep the personal files or nothing.

Then I found this question saying that you need to remove the language packs but it still doesn't work.

The current Windows display language is English (Canada) in the PC Settings. I downloaded the Windows 8.1 enterprise update (English) .iso

There are English Uk and English but no English (Canada) on the MSDN download website.

I don't know if it could be the problem

Solution

You cannot perform an in-place upgrade from a plain-jane Windows 8.1 to 8.1 Enterprise; you need at least Windows 8 Pro.

From Microsoft's Windows 8 and Windows 8.1 Upgrade Paths:

You can upgrade to Windows 8.1 Enterprise (Volume License) from the following operating system editions:

• Windows 8 Pro
• Windows 8 Pro with Media Center
• Windows 8 Enterprise
• Windows 8.1 Pro

The language and region must match exactly to upgrade from any version of Windows 8.0 to Windows 8.1. Once you do that you can upgrade to Windows 8.1 Professional through the utility. But you can't use the utility to go from Professional to Enterprise anyways.

Shame I requested my last key for 8.1 enterprise. All I need is bitlocker and it's avalaible with Windows 8.1 Pro. Thank you

You also can't upgrade to Enterprise through the Add feature to windows utility anyways. You can do an in-place upgrade following the supported upgrade paths though.

I managed to get a key for Windows 8.1 pro and it works! Thank you!
