Trying to upgrade a server I ran into the following message:
You can’t do a typical upgrade using an installation disc that’s different from the language installed on your computer.
- Windows Server 2008 R2
- Installed with a German DVD
- English Language Pack installed
- UI language is English with German number formats
- Windows Server 2012 R2
- English DVD
Interpreting the message literally it appears to be false: The English language is installed contrary to what the message says.
What can I do to in-place upgrade the OS?
I'm testing the upgrade in a VM that was created from a server image. I'm open to performing experiments.
