The SMEX Agent was updated from SMEX-12.0-SP1-Patch1-1727 to Patch2_1782. After the update, the Master Service was not able to start. It also stopped reporting to the Control Manager (TMCM) server.
The presence of a certain registry key "CWDIllegalInDllSearch"=dword:FFFFFFFF removes the current working directory from the library search path. It then prevents the SMEX Master Service from starting. It should be removed in any of the following situations:
- Before installing or upgrade SMEX
- Before installing or uninstalling a hot fix, a patch or a Service Pack
- When SMEX crashes unexpectedly, and is unable to start automatically
