I downloaded the window version of vuforia SDK (vuforia-SDK-android-1-5-9.exe) from Qualcomm website. But when I run it, I got the following error: "The version of this file is not compatible with the version of Windows you're running. Check your computer's system information to see whether you need an x86 (32-bit) or x64 (64-bit) version of the program, and then contact the software publisher."
My computer is runing Window 7. It can run 32-bit or 64-bit program.
How to slove this problem? Your helps are much appreciated.
