Hi,

I want to exit out of the installation in a certain condition.
For eg. Checking the OS.
I am putting the code for the Checking of OS/locale in a MSI based dll and placing it in the sequence in such a way that it appears before any other installation screen starts.

I am returning the ERROR_INSTALL_FAILURE, but then this brings up the Setup Error dialog. I do not want to show this dialog but some other customized dialog of my own and then exit.

Is there any way I can do this??

Or Is there a silent exit by which no screens from the installer are shown to the user on exit. I can put my own dialog in the MSI Dll.

Thanks

I think by default, Windows installer will pop up an error box when a custom action returns an error.

What your could do is run your custom action, and let the custom action set a property, BUT always return success.

You can then have the dialog logic look at this property and show the correct dialog when the property is set to the correct value.

Yeah, in the Custom Actions view in Installshield, select the custom action in question and set the Return Processing to "Synchronous (Ignores exit code)". This will prevent Windows Installer from aborting the setup regardless of what the custom action returns.

Note! If you want the custom action to be able to abort the setup, then you of course need to check the exit code!
