Detect if a VB6 App is Running on a 64 bit Operating System
Version Compatibility: Visual Basic 6
This is a simple set of functions to determine if your VB6 (32-bit) code is running on a 64-bit windows operating system, using WOW64. I have tested it on W2K SP4 Server (32-bit), XP Pro (32-Bit) and W2K3 SP1 Server (64-Bit).
Instructions: Copy the declarations and code below and paste directly into your VB project.
