Software Deployment

Has anyone tried to repackage Visual foxpro 9?

I'm having all sorts of bother. The setup.exe which launches the msi doesn't seem to recognise any command line switches (all the documentation says is double click the setep.exe) e.g can't create admin install.

I've Tried removing the condition from the msi (via a transform) to enable it to run independant of the setup.exe, this also means removing the uninstall keys which launch the exe. This seems to work but because the msi has no dialog wizards repair and maintenence is not possible

Also the msi doesn't self repair (even when installed properly through the setup.exe)

Any advice would be much appreciated
