SUMMARY
The Visual Basic 6.0 family of products are designed to run on 32-bit versions of Microsoft Windows operating systems. When you run any of these programs on a 64-bit version of a Windows operating system, the program runs in the 32-bit layer of the Windows operating system known as Windows on Windows (WOW).
MORE INFORMATION
Microsoft developed Visual Basic 6.0 before the availability of the IA-64 and x64 operating systems. Because 32-bit applications run transparently in WOW, the experience should be identical to running on a native 32-bit operating system. Although Visual Basic 6.0 should run without any issues in 64-bit environments, you may experience unexpected behavior in rare instances.

You may experience an issue when you run a program that was created in a Visual Basic 6.0 product on a 64-bit version of Windows. When you obtain support for this issue, you should note whether the issue also occurs when you run the program on the equivalent 32-bit version of the same version of Windows.

Because 32-bit applications run in WOW, you should experience a negligible difference between 32-bit and 64-bit environments.
