Hello to all I'm aware to the fact that many threads were created on this issue, But I have not found a proper solution so far. I have installed the CU4 on a fresh SCOM 2007 R2 machine, and following Microsoft instructions : http://support.microsoft.com/kb/2449679 Generally what I did was this : 1. Extracted the package 2. The install .hta started automatically 3. clicked the "Update Server" 4. First Setup process started, when it finished I click Finish 5. Second Setup process started, when it finished I click Finish 6. The setup turn of the SCX agent platform (KB2449679-x86-SCX.msp and KB2449679-x64-SCX.msp) failed stating : "upgrade patch cannot be installed by the Windows Installer service because the program to be upgraded may be missing..." Tried to look for a LOG file in %temp% - did not found any. Tried to create a log file using the msiexec.exe with the /l option, did not created any logs. Tried to extract the files from the .msp file, did not work. Tried to look for errors in Windows event log - did not find any. Well, The cross platform agents remained in the same version as : scx-1.0.4-248.solaris.8.sparc.pkg.Z and not up upgraded to the 1.0.4-265 as described in the CU4 document by Microsoft : "For example, the following is the file name format for the agent for SUSE Linux Enterprise Server 10 (x86): scx-1.0.4-265-sles.10.x86.rpm" Somebody faced this problem ? Any one has a solution ? Thanks a lot, Guy

Hello All After getting support from Microsoft - It is probably because the SCOM 2007 is in EVAL version installing the normal version will fix this Guy

Thanks for updating this - if it is ok, I'll close the thread now. Cheers GrahamView OpsMgr tips and tricks at http://systemcentersolutions.wordpress.com/
