I've never seen that, but you could try running a site reset.

On the ConfigMgr site server, what value you see under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\ConfigMgr\Setup\Full UI Version ??? Have you upgraded from ConfigMgr RTM/SP1 to SP2 version ??? If yes, there are no errors in the ConfigMgrSetup.log ???Microsoft MVP - SCCM

I'm assuming that you are talking about your "test" site because installing FEP into a production environment is not supported and not a good idea. Also, if it shows a different version number, then that's the version you are probably at. Are you looking on the console on the site system or a remote console? Did you install from media that (supposedly) contained the SP integrated or did you later install the SP?Jason | http://myitforum.com/cs2/blogs/jsandys | http://blogs.catapultsystems.com/jsandys/default.aspx | Twitter @JasonSandys

Please have a look at http://technet.microsoft.com/en-us/library/bb694286.aspx to see how to initiate a site reset.

Really it's very strange, I've never seen that, I don't want to say you "remove/re-install ConfigMgr" because I would like to know the cause of this issue :( Have you tried to see the site version from a remote console ??? Microsoft MVP - SCCM

I uninstalled sccm and reinstalled still have the same problem although when the install finished it look like not all the items have a green tick here's a screen shot http://img205.imageshack.us/img205/8016/sccminstall.png
