>>Yes, but it requires low-level file access from a spawned remote process that does the update once the application has terminated. It's a simple matter of opening the .EXE, locating the table within, and doing the update. You'll need to add markers that you can explicitly search for within the .EXE, use FILETOSTR() to load the .EXE file, make the change with STUFF(), and then STRTOFILE() to write the .EXE back out.

You're also likely to run into snag if the program was installed under "Program Files" (on 32-bit) or "Program Files (x86)" (on 64-bit)...
