Was doing a Proof-of-Concept yesterday on McAfee EPO 4.5 on Windows 2008 R2… and sad to say that it is not supported yet. Though there are tweak(way) to bypass the OS check and install the EPO4.5 onto Windows 2008 R2, I choose not to as it is not advisable since McAfee indicates that they will be releasing Patch 1 for EPO4.5 to overcome this issue by Q4 2009.
To balance the need and risk, it would be better to let the client to grab the update from the internet (Only less than 50 clients) than to risk the fact of installing EPO4.5 onto Win2008R2 server and vote any support.
Now.. I am wondering Q4 of 2009 is Dec or 2010 March? Haa… Just hope that McAfee will release the version ASAP! :)

For those who are interested on the tweak, following are the links. I have tested and it seems to work.
