I developed a plug_in for Acrobat and the Reader. For deployment I made an Windows installer, which copies it into the plug_ins folder. This works well. But I the user updates the Reader from 8 to 9 or 10 , the installation folder changes from "Adobe\Reader 8.0" to "Adobe\Reader 9.0". The problem is now that the deinstallation from my plug_in does not work anymore. That's because the name of the parent folder has changed, and my installer has no chance to detect this change.
Has anyone experienced this problem? Is there a solution for that?
Thanks for help or some hints.
