I'm trying to install MEP 2014 on my Win 8.1 machine from disc. It gets to Creating instaltion script and just hangs. I eventually eject the disc and Cancel the request for me yo put it back in and get an "unknown" error message accessing MxSetupRes.dll (probably because I've ejected the disc).
The disc looks undamaged.
Is this a known issue with Win 8? I can be sure I've ever install 2014 on Win 8.1 - I had it on a Win 7 laptop before.
