When I tried to register a COM DLL,
regsvr32 rpcrt4.dll
I get the following error message:
`The module \"c:\\windows\\system 32\\\
Use following command should work on windows 7. don't forget to enclose the dll name with full path in double quotations.
C:\Windows\SysWOW64>regsvr32 "c:\dll.name"
Open the start menu and type cmd into the search box
Hold Ctrl + Shift and press Enter
This runs the Command Prompt in Administrator mode.
Now type regsvr32 MyComobject.dll

Run it in a elevated command prompt.
