The Call to DllRegisterServer Failed with Error Code 0×80004005 on Windows Vista

To register a DLL in Windows Vista with regsvr32.exe, you need to have administrator privileges and rights. Unless you have disabled UAC (User Access Control), all user accounts except Administrator that you use to login into Vista will need user to manually elevate the user rights to administrator credentials although you have set their roles as administrator.

If you try to regsvr32 a module in normal command prompt window without proper administrative privileges, you will get the following error message:

The module “xxx.dll” was loaded but the call to DllregisterServer failed with error code 0×80004005.

The scenarios that this error may occur are when you trying to register the jscript.dll or vbscript.dll to solve internal error 2739 during installation, or when install add-ins for Microsoft Outlook 2007 such as TRSOutlookAddin.dll or other DLLs under Windows Vista by using regsvr32.exe.

To solve the call to “DllregisterServer failed with error code 0×80004005″ error, run a Command Prompt as Administrator. Alternatively, you can disable User Access Control too, or login with Administrator account.

    If there are no other errors have you tried registering it with an elevated command prompt?
    (Start, All Programs, Accessories, right-click Command Prompt, and then click Run as Administrator)
    Then use regsvr32 to register the DLL

    Thankyou! Ran a command prompt as administrator and worked brilliantly. Like apis17, I forgot about the admin level, and the installation guides never mention it themselves.
