With Windows 7, will programs that were made for 32-bit Windows 7 still work on the 64-bit version?

32-bit and 64-bit Windows: frequently asked questions

"Can I run 32-bit programs on a 64-bit computer?

Most programs designed for the 32-bit version of Windows will work on the 64-bit version of Windows. Notable exceptions are many antivirus programs.

Device drivers designed for the 32-bit version of Windows don't work on computers running a 64-bit version of Windows. If you're trying to install a printer or other device that only has 32-bit drivers available, it won't work correctly on a 64-bit version of Windows. To learn how to check for drivers, see Update a driver for hardware that isn't working properly or go to the device manufacturer's website. You can also get information about drivers by going to the Windows 7 Upgrade Advisor webpage."

Generally yes. Some software might not, though, and a lot of anti-virus software is known not to work on both versions of Windows 7.
