GIMP :: Won't Automatically Use Epsonscan To Create Images

When I try to create a document, Gimp finds my web cam, but not the twain driver. The scanner is a perfection 636U. When I click on "create>scanner/camera", it gives me a Twain.exe system error - error message that reads:

"The program can't start because PMDD32F3.dll is missing from your computer. Try reinstalling the program to fix this problem."

Some more info that might be useful:

If I go into epsonscan directly, it finds the scanner and scans just fine. I can export the image and open in Gimp just fine.

The laptop is a win7 machine. There are no Win7 drivers for the scanner. I am using some Win2000 drivers that I used to use in XP with no issue.

The PMDD32F3.dll file is in the Windows>System32 file

I'm at a loss on why epsonscan works itself perfectly, but not in Gimp like it does on my XP machine.
