On the failed target, go to Services / RSCD Agent Service / Properties, on the "Log On" tab check "Allow service to interact with desktop", restart the agent.All systems are set up differently, and some systems may work without that option checked, where others need this option.
If during the Analysis run the c:\Trace.txt is not generated, and the above did not help, then try this option:
From command line of your appserver (or any NSH prompt) run the following:
nsh-prompt% nexec -n target "C:\Program Files\BMC Software\BladeLogic\RSC\sbin\BLPatchCheck2.exe" (correct path if needed)
Expected output is BLPatchCheck2 “usage” information, but if you see this instead “ERROR: my_memexec PATH too large”, then review the following KB: https://kb.bmc.com/infocenter/index?page=content&id=KA323583
