I am trying to install the windows 2012 eval version, I downloaded

9200.16384.WIN8_RTM.120725-1247_X64FRE_SERVER_EVAL_EN-US-HRM_SSS_X64FREE_EN-US_DV5.iso from http://technet.microsoft.com/en-US/evalcenter/hh670538.aspx

burned a disk but when I try and install it asks for a key, and from what I understand this should not require a key.

I got this from Microsoft <Microsoft@e-mail.microsoft.com>

can someone tell me why this is happening?

Sounds like either your download or your burning munged something.  I use the eval copy all the time and have never been asked for a key.

Having the same problem as Eric. Unlikely that is has anything to do with downloading or DVD burning. I have downloaded the ISO before, using the same MS account. At that time I received a mail from MS specifying a product key. That key does not work on the second installation.

Hi Tim,  I respect your knowledge.  Yet I am having this difficulty also.  In my case I do not think it is the iso that I burned to disc because I burned two discs and each had the problem.  I downloaded the ISO for each.
