Hi All,
There is a third party product already installed on user's system. I
created an install that adds some extended functionality to that
existing product. For that, my install has to replace several .asp/.js
files. My add-on installs just fine, and the new extended functionality
is there. However, when I uninstall my add-on, it deletes those .asp/.js
files, which should not happen, as they are vital for that third-party
product, which of course does not work anymore after my add-on is
uninstalled. I don't have any control over that product, just my own
install package.
The question is: should I implement some custom action to back up
existing files, then copy my own files, and then on uninstall restore
copies from backup. Or is there some built-in mechanism in Wix to create
a backup of existing files?
Thanks!
