unable to install application

I am attempting to install an application that I have install hundreds of times before, but am now getting errors.

Please note that this occurs on a computer that was upgraded from Windows 98SE to Windows 2000 Pro and AFTER the computer was joined to the domain.

I have an application that I have been able to install on Windows 2000 before with no problem. I have upgraded several other computers to 2000 and the application was installed no problem. But on this particular computer, it simply will not install. It is a faxing application that creates a local printer (just like Microsoft Fax). So when the user prints a Word document to this printer, it actually sends it to the fax server, which the converts the document to the correct format for faxing.

The error that I get is "Error calling AddMonitor (0x7f)", followed by "Setup Failed". A call to the manufacturer proved futile as they have never experienced this.

I have tried removing the computer from the domain and adding back to the default workgroup that I saw before joining to the domain, again with no success. I tried logging in as the domain admin and running the install, logging in as the local admin, again with no success.

Have I missed a step?

Try installing on this computer while logged on as the Administrator to the domain.
Also, reset the user to Admin on the PC and Power User on the domain in Control Panel, User Accounts.

I will be "giving" the points away. The solution was found in two remnant dll files that would always remain, even after uninstalling the software. It took quite of while of hunting (and registry removals), but once these two files were deleted, I was able to do a normal installation, which was then able to properly create the printer & printer port.
