In BeforeUnistall method session.CustomActionData is empty when unistalling. But in AfterIntall method all parameters exists.
What is my problem? What is wrong?

Answer 1

I resolved my problem. I store path in registry and get it on uninstall.

Answer 2

Windows Installer doesn't persist properties after an installation completes. You need to do it yourself such as this example.

IsWiX generated projects include boilerplate code as an example here.
