Hi MikefromOhio,
This error message will be displayed if the regsvr32.exe command is not run as an administrator on the Windows 7 computer.
Error code 0x80070005 generally refers to the “Access Denied” error message.
Trying logging into an administrator account and register the file again and check.
Execute the regsvr32.exe command as an administrator of the Windows Vista computer.
1. Click Start, point to All Programs, click Accessories and then right-click Command Prompt.
2. Click Run as administrator. If you are prompted with a logon, enter the Administrator credentials. Otherwise, click Continue to authorize the action.
3. Within the Command Prompt, type regsvr32.exe and then type enter the path of the .dll file to be registered. (regsvr32.exe C:\Windows\syswow64\msxml4.dll)
How do I run an application once with a full administrator access token?
