I need help installing ACP Planner on my Windows 7 Pro, 64-bit system. I ran the installer as the administrator and the error message reported:

"The version of this file is not compatilble with the version of Windows your're running. Check your computer's system information to see whether you need an x86 (32-bit) or (x64 bit) version of the program, and then contact the software publisher."

Here is part of the Windows Application log file:

The program or feature "\??\C:\Users\fparks\Desktop\ACPPlanner-4.2-Setup.msi.exe" cannot start or run due to incompatibity with 64-bit versions of Windows. Please contact the software vendor to ask if a 64-bit Windows compatible version is available.

This error terminates the installation process.
I have successfully installed and run TheSkyX Pro and also ACP on this machine.
