I have two types of computers. Win7 64bit laptops and Win7 64bit Desktops. For some reasons the desktops are showing up in SCCM as status N/A instead of Approved. On the desktops the %windir%/ccmsetup directory has the ccmsetup.exe and when I try to run it with the /uninstall switch it errors saying that I need a 64bit version. If I go into the Control Panel > System and Security there is a Configuration Manager 32bit option at the bottom. I'm not sure how these desktops are getting the 32bit client and my laptops are getting the 64bit client, but I would like to remove the 32bit one and try to get the right client on them. I'm using WSUS / software update point for client distribution.

There is only 32 bit client for ConfigMg, so ther is no need to do anything. What I would look at is why are the PCs not getting approved. http://www.enhansoft.com/

About 30 minutes after posting this I realized that exact point. I thought there was supposed to be a sccm service though, but after looking at the log in %windir%/ccmsetup I see the service is removed during install. What should I do to tell why some machines are status not approved?
