Problem: Mac OS 9 has limited user access options to access specific programs only. When trying a scan a document in Photoshop, the Epson TWAIN device doesn't show up. Other scanners work because I installed the specific TWAIN driver inside the Photoshop folder, but Epson has an automatic install program that doesn't provide the Plug-In separately. I tried enabling the TWAIN program, but I can't launch it because it says some extension or control panel is missing. How would I enable everything it needs?
