Hi there,

Are there any utilities or APIs which allow modification of an installscript installation’s uninstall information?


Basically the situation is this:

We will be doing an installscript install, but will be using a home grown patch system for upgrades. We would like something that allows us to install with installshield, patch a few times, possibly adding, removing and changing files. And then run uninstall and have everything be wiped out (perhaps not user created data ). Is this something that can be done? And how would we go about doing it?

Thank you very much.

Cheers,

Dave

You could add code to your script to delete any additional files during uninstall, like deleting all files in a directory.

Interesting idea.. it initially had me really excited, but what happens if the user installs the product to somewhere less than ideal i.e. c:\program files\ instead of c:\program files\myapp.

Yes this allows me to clean up all of my subdirectories, but if something gets added to <install dir> between patches then i can't quite clean it up. ( without keeping a list somewhere of what i've added, and having that get called in a custom uninstall action. and if i'm doing that then what's the point of the uninstaller anyway ? )

You could enforce a proper installation path by requiring that the folder contains no prior files or folders.
