You can also use the following to register a DLL or OCX.

lcFile = "C:\WINNT\System32\COMDLG32.OCX"
DECLARE INTEGER DllRegisterServer IN (lcFile)
llsuccess = (DllRegisterServer() = 0)
IF llsuccess 
    DO LogEvent WITH "Registered: " + lcFile
ELSE
    DO LogEvent WITH "Could NOT Register: " + lcFile
ENDIF

>I then scan the table and compare the list of files to what's installed on the user's local drive. I then copy any files needed and RUN REGSRV32 to register any components that need it.
