I am trying to register a DLL and receive the following error message: .....DLL was loaded but the call to the DLLRegisterServer failed with error code 0x80004005.
Can someone help by providing a proven, tested resolution, as I have exhausted all the what-ifs I have found searching the Web?
The attached document shows the error messages in both Word and Windows. The Word interface used in relation to the add-in is also shown. The system specifications are shown.
Windows 7 Professional 64-bit Service Pack 1
Home computer, not a networked computer. I have administrative privileges.
UAC is turned off.
Microsoft Office Professional Plus 2010 (Word)
The DLL is related to Nuance PDF Converter 7.3 software. It is an add-in for Microsoft Word. The technical support folks with Nuance have been very helpful but unable to find a solution.
I think the problem is with Windows, i.e., the prevention of loading of the DLL.
I have searched the Web endlessly. I see a number of posts regarding the error message, that is, the same problem. I have found no solution that works, having tried many.
I have searched Experts Exchange. I have tried all suggestions that I found.
I have tried the following:
Ensured the DLL is in the path used with the register command.
Disabled the Windows firewall and anti-virus software.
Tried to add the DLL to Word’s add-ins using Word’s options.
Run the register DLL command at the command prompt as an administrator. That is, I used an elevated command prompt.
Run the register DLL command in the Run dialog box as an administrator.
Run the register DLL command in Safe Mode using the command prompt and as adminstrator.
Uninstalled the software multiple times.
Repaired Microsoft Office (Word) multiple times.
Run the register DLL command after each repair attempt.
Uninstalled and reinstalled Office.
Tried running the unregister DLL command as well. The error is the same.
Checked security on the DLL file. As the user, I have full control. Set up Everyone with full control.
The software is installed on another computer with the same operating system and Office 2010. There is no problem with the DLL.
I am using the commands below to unregister and register the DLL. The error message each time is essentially the same.
