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.
