WiX installer registry keys get removed at shutdown/restart

Question

Here is my xml file for WiX https://github.com/Vaei/ue4cleaner/blob/master/UE4Cleaner/UE4CleanerInstaller.xml

The registry keys get installed and everything works beautifully until restarting the computer, then they get removed. If I do a bad shutdown (hold the power button or press reset on the case) it will remain.

Answer 1

The dirty shutdown scenario suggests to me that you have some running processes that are deleting the registry data when windows tells them to shutdown. I don't think this is an installer problem at all.
