Why does MS not post some sort of hashsums such as SHA1 or MD5Sums of this trials of their various server products? I downloaded Server 2012 and Server 2012/R2 and tried to install them into VMWare Workstation 10 only to become frustrated due to strange error messages. I thought perhaps that the downloads were corrupted and went to look for MD5Sums for the downloads but gave up in frustration.

I downloaded both of these files all over again aka over 6GB of files only to discover that it made no difference! Why on earth doesn't MS post check sums for all of their large downloads rather than frustrate their end users?

There appears to be a problem with installing the x64 ISOs in VMWare workstation. I had no problem installing Server 2012 in Virtualbox 

I haven't had any issues like this installing on ESXi, maybe they know more over here.
