U NEED to have Adobe Photoshop 32 bit installed. It will NOT work with 64 bit. If ur OS is 64 bit just go to C:ProgramFilesx86/Adobe/Adobe Photoshop. Search for Photoshop.exe and send a shortcut to desktop. The just drag and drop ur .DtX file on ur Photoshop 32 bit Shortcut. Of course your Photoshop 32 bit also needs the Plug Ins installed.
