Unfortunately, you can't download a PDA Export Plugin compatible with Windows 7 because there isn't an online resource available for this purpose. From what it seems, the application has been discontinued and it is no longer supported. However, you can try to run the 1.1 version of the plugin using the Compatibility Mode. Right click on the program icon and go to Properties > Compatibility tab. Check the Run this program in compatibility mode for box and select Windows XP from the drop-down list. Click Apply and then OK.
