server 2012 vmware workstation 9 error on install

Hmm. Should I be able to deploy a server 2012 R2 from an ISO into a VMWare workstation 9 environment? Just trying to get some hands on for exam prep.
When i tried installing i chose the "i will install OS later" option, rebooted, pointed virtual CD at iso but i get an error - please see attachment if you can.
Any help appreciated.

ps, i can deploy 2008 R2 servers in the same workstation build.

which ISO file of Windows Server 2012 are you using? have you checked its SHA-1 hash to verify the ISO image before using it to install the OS?

Hi, i still have an active technet account so have just downloaded the ISO file called "en_windows_server_2012_r2_with_update_x64_dvd_4065220"

I read something recently about checking the SHA-1 hash, at the risk of sounding dumb can you advice how this is done please? I assume you are checking the authenticity of the download?
Thank you.

We’d all like to think our company’s data is well protected, but when you ask IT professionals they admit the data probably is not as safe as it could be.

Thanks for that. I can see how to run the utility against the iso file but where do I get the original value from Microsoft to compare it against?
bbaoIT ConsultantCommented:
you didn't see the SHA1 code when downloading the ISO file from Microsoft? anyway, see below the screenshot.

its SHA1 code is AF9EF225A510D6D51C5520396452D4F1C1E06935
