I have Windows 8.1 Enterprise and I wanted to install the Windows 10 Enterprise evaluation (from https://www.microsoft.com/en-us/evalcenter/evaluate-windows-10-enterprise). I don't want to wait until the IT team at our company decides to give us the official update and I rather just install it and in a few weeks I'll get the key from them.
Now, I downloaded the evaluation version ISO but when trying to install it (mounting the ISO file and double clicking setup.exe) it tells me that the versions are different and that I cannot keep any of my files or apps if I continue.
Both versions are Enterprise 64bits and both are in English (US).
Any idea of why that might happen?

Updated: Misread the earlier version; updating to reflect further research.
According to the Windows 10 Enterprise FAQ for IT Professionals, you should be able to perform an in-place upgrade:
(See the second question in the Administration section)
I've looked at a few different public support forums for related reports and there do not seem to be a widespread problems with inline updates for Win10 Enterprise evaluation. I did find one report mentioning that it seems to occur when choosing different country/locale settings than were originally selected.
Traditionally, in-place updates become possible later in the development cycle. Depending on when you downloaded your .ISO (or when it was last updated on your source), it's possible that in-place upgrade is not fully complete.
Since a new evaluation version is either imminent or shortly to be released, perhaps trying again later will provide a cleaner experience.
For those attempting to install the "free upgrade" binaries, per the Windows 10 FAQ:
(See the answer to "What edition of Windows will I get as part of this free upgrade?")
In other words, I don't think you'll be able to upgrade Enterprise using the free upgrade installation binaries.
Hope this helps...
