I'm having problem patching on a RTM + SP1 based master.
I have the file version of the file incremented, higher than that of the previous SP1.
The patch works perfectly on RTM but not on RTM +SP1.
I cannot find the SELMGR error in the log file.
ProductVersion of the upgradedImage is incremented. ProductCode remain.
I did not see the line, Caching "Component" from "location" for baseline 0 in my RTM + SP1 log.
But for RTM log file, Prior to the caching statement, I see that there is this Action start InstallFiles. for successful patching.
Please advice what could be the problem.

Thanks,
