KB38939: How does the Component Registration check verfiy missing or unregistered DLL, OCX and EXE files in MicroStrategy Health Center?

The Component Registration check verifies that all .EXE, .DLL, and OCX files required by Desktop, Intelligence Server and Narrowcast are present and properly registered on a Windows machine. It reports two types of error:

• If any files are missing, Health Center provides a list of those files. This should be addressed by fresh or repair installation.
• If any files are not registered correctly, click the link provided to register them.
   
  

The system check first goes through two registry locations and find a list of files required to be installed by Strategy versions. Here are two registry locations:

• HKEY_CLASSES_ROOT_CLSID
• HKEY_CLASSES_ROOT_TypeLib

Health Center retrives a list of EXE, DLL and OCX files specific to each Strategy versions by checking XML files stored under Health Center HOME folder:  \Common Files\MicroStrategy\Health Center\plugins\com\MicroStrategy\tools\mcdgnstc\plugins\conf
 

 
Each DllValidationList_9.x.x.xml contains list of files searched by the system check. There are four corrective actions if there are files not registered properly:

1. If the system check detected there were unregistered dlls, it will go through the list of unregistered dlls and register them one by one using Regsvr32.exe /s command
2. If the system check detected there were dlls registered in the wrong location, it will go through that list to first unregister the dll using Regsvr32.exe /s /u command, followed by registration using Regsvr32.exe /s  command
3. If the system check detected there were unregistered exes, it will register each exes in that list using <exe name> /regserver command
4. If the system check detected there were unregistered assembly dll, it will register them using RegAsm.exe /s command.
