Just installed SCCM 2007 SP2 (4.00.6487.2000). When trying to install R3 on top of it, I got the message saying HotFix KB977384 is need. The hotfix has been downloaded and unzipped. However, when double-click the SCCM2007-SP2-KB977384-ENU.msi installer, it was prompted "Please run the installer with elevated privileges". The current logon account is a member of domain admins group and thus a member of the local administrators group. Moreover, right-click the installer it does not give me the "Run As" option. So it end me up with no way to install this hotfix. Please help.

Try launching the installation from an elevated command prompt. Regards, Jörgen-- visit my System center blog at http://ccmexec.com --

This is happening because of UAC. When UAC is enabled, accounts cannot use their admin privileges unless you explicitly launch a process elevated. In this case, as both Kent and Jorgen describe, you must first launch an elevated command prompt and then initiate the installation from there becuase you cannot elevate an MSI as it is not an executable.Jason | http://myitforum.com/cs2/blogs/jsandys | http://blogs.catapultsystems.com/jsandys/default.aspx | Twitter @JasonSandys

Thank you all for the advice. I now installed the hotfix from an elevated command window. But again, when I trying to install R3 I received the message saying: "The system administrator has set policies to prevent this installation." So do I need to launch the R3 installation from an elevated command window again? (what command to launch .hta?) The logon account I used is the same one used to install SCCM 2007. Why R3 need a higher priliveged account?

Because of UAC as I spoke about above. Some things can trigger elevation properly, some can't. MSPs can't (which is what the hotfix is distributed as) and neither can HTAs.Jason | http://myitforum.com/cs2/blogs/jsandys | http://blogs.catapultsystems.com/jsandys/default.aspx | Twitter @JasonSandys
