I just tried the troubleshooter, and it said it fixed the issue but it actually didn't: when I run the program, Windows pops up a modal (before it just displayed an error on the console) with a title bar that says "Unsupported 16-Bit Application" and a message reading, "The program or feature [...] cannot start or run due to incompatibility with 64-bit versions of Windows. Please contact the software vendor to ask if a 64-bit Windows compatible version is available."
