The DllRegisterServer returns 0x80070005

Question

I coded a H.264 directshow-based decoder. I register it by running the "regsvr32.exe diavc.ax" and it succeeds. But some users report that it fails with the following message:

The module "diavc.ax" was loaded but the call to "DllRegisterServer" failed with error code 0x80070005.

How can I solve the problem?

The next code is the "DllRegisterServer", it is very simple.

STDAPI DllRegisterServer()
{

    return AMovieDllRegisterServer2( TRUE );

}

 

Answer 1

What are your dependencies?  Did you statically link to the CRT to avoid a dependency on the CRT DLL's?

If they are running Vista/Windows 7 make sure they elevate to UAC Administrator privileges before attempting to register.

Yes, the filter is staticly linked to CRT to avoid a dependency on the CRT dlls.

That's E_ACCESSDENIED. Does this happen on Vista and Win 7 systems? If

so, the problem is likely to be UAC and the need for elevation.

Tell your users to launch the command prompt window with a right click, "Run as administrator". The they can enter "regsvr32.exe filtername.ax"
