I'm storing information in a custom property sheet for one of my custom products (I'm then using that information in a javascript file). I want this product to uninstall cleanly, but I can't seem to figure out how to remove a custom property sheet on uninstall using genericsetup. I know that remove="True" doesn't work, but I'm not having much luck figuring out the correct way (or any way for that matter) for removing this. Any suggestions would be greatly appreciated.
This is confusing for at least two reasons:
We have both "old style" and "new style" technologies actively in use. Old style refers to Extensions/Install.py (Python code) and new style refers to profiles/default (GS XML + setuphandlers.py Python code).
Successfully installing and uninstalling add-ons in all possible cases still requires the use of both old and new style technologies.
If you don't care about uninstall, you never need to use Extensions/Install.py. If you do care about uninstall, create an Extensions/Install.py with install and uninstall methods.
Also create an "uninstall" profile (in addition to the "default" profile) e.g. profiles/uninstall. Configure the Extensions/Install.py:install() method to execute your "normal" profiles/default steps on installation. Now comes the "fun" part.
Because some technologies can be uninstalled "properly" via GS i.e. they respect the remove=True parameter, your Extensions/Install.py:uninstall() method should execute the "proper" GS profiles to do the uninstall. But if your add-on uses technologies that cannot be uninstalled "properly" via GS i.e. those that do not respect the remove=True parameter, then you will need to write Python code to perform the uninstall.
