I have installed Forefront Endpoint Protection 2010 a couple of times now and I must say that the system requirements document on Technet has a complete list of pre-req’s, read it before starting the installation. http://technet.microsoft.com/en-us/library/ff823830.aspx
The installation it self is really straightforward if all the system requirements are fulfilled.
However almost every installation of either the server or the console extensions, the “Prerequisites Verification” step fails on the “Verifying a restart is not required” action.
On a couple of the computers/servers a restart solved it but in some cases there where other installations which haven’t cleanup the following registry key which is the key or file rename operations which has failed.
If that key is present the installation will not continue.
- Rename the registry key (that way you can put it back if needed)
- Install Forefront Endpoint Protection
- Put the key back if you think it could be needed
