"Setup.exe is not a valid Windows NT Application".

[adzheng]

When I run somebody's Setup.exe which is built by IS from my Windows NT Embedded System (Minimum Installation), I got an error "Setup.exe is not a valid Windows NT Application". But this would not happen when it runs under Win2K or Windows NT Embedded System with Standard Installation. I thought it is due to some privilege with NT and IS Setup can not execute. But don't know why and how to fix it? Maybe need to install more components? Any help will be highly appreciated!

I suspect that the setup was built using 16 bit setup.exe. Some systems are configured to not allow execution of 16 bit apps. If you check the properties of the setup.exe you can see whether it is 16 or 32 bits. If you are using Installshield 5.5 then you can use "32 bit setup.exe" option in media build.

I have managed to get NT4.0 SP6 to run a 16bit InstallShield setup.exe without a problem. Would that just be some 16bit setups then???

Thanks for U guys reply!

The problem is I'm trying to use this installation under WINNT Embeded System with Minimum Installation which only has minimum components installed in NT System. In the Standard Installation System, this Setup.exe can run even under SP5. So I'm wondering that in order to run the 16Bits Setup.exe, the system needs any components support? or Maybe System needs any "Configuration" to be able to run 16Bit Setup? And how to do with it?

PS. I got this Installation from another company without source code, so I can not change it to 32Bits App.

Any suggestions are highly appreciate!
