Hi There:
I would like to silently uninstall a non-msi legacy installation from a msi-based project. I created the setup.iss using setup.exe then called setup.exe /s /f1"setup.iss". However for some reason this does not work..even calling setup.exe from the command line does not work.
Am I doing something wrong? Please help...

Thanks in advance

Did you generate the .iss file for the uninstall (not for the install)?
What results (error codes) do you get? Where is your .iss file located?

Thanks for the reply Stefan..
I figured out how to do it...
I've actually generated the .iss and called LaunchAppAndWait with the uninstall command line that I extract from a registry entry written by the previous installation.
I called this in a custom action..
There are still some issues like: the next custom action executes while the uninstall runs, but this a limitation of of LaunchAppAndWait which waits for window-based applications to finish...in my case it is a silent uninstall, hence no window.
But I'll find a work around...
