I have an old app that some people still are using, and most have been able to install it in Vista with no issues.

However, this one client get's this error:

"The version of this file is not compatible with the version of windows you are running. Check your computer's system information to see whether you need a x86(32bit) or x64(64bit) version of the program."

This older FPW app uses the installer the Microsoft included with FPW, and another part of the app uses a Wize installer. Both of these setup's give the same above error. I have had him boot in Safe mode and attempt install, as well as turning off User Account Control. Neither of these helped.

Any suggestions?

His system info is as follows:

Computer System Information
Windows Edition: Windows Vista Home Premium
Copyright 2007 Microsoft Corporation
Service Pack 1

System
HP a6708c
Intel(R) Pentium (R) Dual CPU E2220
64 bit operating system

Thanks for the help.....
