I have a Foxpro application developed on a Windows ME system. Created the setup.exe and associated installation files from a Windows ME machine. When I use use the setup files to install the application on a Win Xp machine, it says Can't run 16-bit applications and insufficient memory.

Anyone know why ?
Thanks

Your running a 64 bit windows xp that is backwards compatible with 32 bit apps but not 16 bit apps.

Also found this at the site that follows:

Give 16-bit apps their own separate processes

[HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Control \ WOW]
"DefaultSeparateVDM"="Yes"

By default, Windows XP will only open one 16-bit process and cram all 16-bit apps running on the system at a given time into that process. This simulates how MS-DOS based systems viewed systems and is necessary for some older applications that run together and share resources. However, most 16-bit applications work perfectly well by themselves and would benefit from the added performance and stability of their own dedicated resources. To force Windows XP to give each 16-bit application it's own resources, browse to HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Control \ WOW and find the String "DefaultSeparateVDM". If it is not there, you may need to create it. Set the value of this to Yes to give each 16-bit application its own process, and No to have the 16-bit application all run in the same memory space.

Anyone know whether applications created by MS Visual Foxpro Version 6.0 for Windows are 16-bit or 32-bit applications. Is is right to say that 16-bit applications are mainly MS-DOS programs and those for Windows 3.1 ?

Thanks and Merry Christmas to all.
