Installing SEPM 11.0.7 on Virtual 2008 R2 Error thinks it is Vista

Hello everyone, my Symantec Endpoint 11.0.7 is currently installed on 2003 server, but is not aquiring new definitions.

I am trying to move it to a Virtual 2008 R2 running on Hyper V, after i installed the IIS v6 support, it is stopping during install with an error that VISTA is not supported. Everything I have read says that 11.0.7 is able to run on 2008 R2.

Could it be that it is a virtual server, and not reporting correctly to the application that it is 2008?

I have never had this issue installing on Virtuals.

Any help would be appreciated, I cannot find anything online for this.
