When you attempt to install a 16-bit application on a computer that runs Windows XP for 64-bit platforms, you may not be able to do so, and you may receive one of the following error messages:
Install.exe is not a valid win32 application.
Setup.exe is not a valid win32 application.
This behavior can occur if the program you are trying to install uses a 16-bit Install.exe or Setup.exe file. Windows XP for 64-bit platforms does not support 16-bit programs.
Contact your application vendor for an updated version of the application that does not use a 16-bit installer.
