### OEM not working after windows patch KB2661254

See the following for more details:
http://blogs.technet.com/b/pki/archive/2012/07/13/blocking-rsa-keys-less-than-1024-bits-part-2.aspx
The above update will block the use of cryptographic keys that are less than 1024 bits. OEM uses a cryptographic key of 512.

The above article shows a workaround as follows:

1. open a CMD prompt,

2. enter the following command:
Certutil -setreg chain\minRSAPubKeyBitLength 512

Alternatively, use Firefox instead of Internet Explorer.
