Why not simply capture the setup to a new MSI (assuming that the EXE doesn't already extract an MSI, that is)?

Yes that can be done. But i want to have generic path variable, if i run msi file on different machine setup.exe should be run, thsts why i am adding files from source to destination computer.

Thanks

My head is about to explode...

I can't see what difference installing on a different machine makes, unless of course you mean that the machines run a different operating system. Even then, you can detect the OS - and the various versions of Windows OS's - in order to determine the installation path, so that doesn't make any difference, either.

Please clarify what your desired end result is. For example, I can't make head or tail of this:

>if i uninstall setup.exe form "Add/Remove Program" while unistalling MSI script the setup.exe will install.

How does uninstalling trigger an install?!?

Is it possible you are running setup.exe by a custom action in the MSI?

If so, you need a condition like "NOT REMOVE", so it wont run on uninstall.

ok thanx for the information.

Need one more help.
i have added a files form source to the destination computer, files contains setup.exe & dependent files for setup.exe. If i run the MSI script installation the setup.exe is woking fine. While uninstalling the MSI script, all files i added from source to destination computer will be removed.
Is it possible the files i added from source to destination computer during uninstall MSI script files cannot be removed.

Thanks Mistral its working fine.
