Windows 7: unable to register DLL - Error Code:0X80004005

Question

When I tried to register a COM DLL,

regsvr32 rpcrt4.dll

I get the following error message:

`The module "c:\windows\system 32\"rpcrt4.dll" was loaded but the call to DllRegisterServer failed with error code 0X80070006.

How do I fix this problem? Please help.

Which error was it, 0x80070006 (as mentioned in the question body) or 0x80004005 (as mentioned in the title)? — stakx - no longer contributing, Oct 10 '15 at 08:03

Has to be the worst error message ever and the simplest fix. – ste-fu Sep 12 '16 at 10:45

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

IMHO that's the best anwswer. You cannot run cmd as `runas /user:Administrator cmd.exe` This will not be enough. You should use this method you explained. +1 for that – jyz Aug 15 '13 at 01:44

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"
