Hi, This is the rubbish I get when I'm trying to upgrade SCCM SP1-R2 to SP2. Problem Event Name: APPCRASH Application Name: SETUP.EXE_System Center Configuration Manager Application Version: 4.0.6487.2000 Application Timestamp: 4ab33f3c Fault Module Name: SETUP.EXE Fault Module Version: 4.0.6487.2000 Fault Module Timestamp: 4ab33f3c Exception Code: c0000005 Exception Offset: 0023e2d7 OS Version: 6.0.6002.2.2.0.272.7 Locale ID: 3081 Additional Information 1: fd00 Additional Information 2: ea6f5fe8924aaa756324d57f87834160 Additional Information 3: fd00 Additional Information 4: ea6f5fe8924aaa756324d57f87834160 Does anyone have any advice please?

Server 2008? UAC enabled? What's in C:\ConfigMgrSetup.log?

Hi, Once, I had this problem and the cause was the antivirus. Therefore, I've disabled the AV and the SP2 installation completed successfully.

I've disabled DEP and antivirus and now I'm good to go. Thanks.
