Hi,

Question:

How do I ensure that all program files are uninstalled when a user goes through add/remove programs?

Scenario:

My setup and deployment project does not remove the following things:

1. Project.exe<br />
2. Project.exe.config<br />
3. The application folder.<br />

None of these things have the permanent attribute nor are they tagged as system files.

So how do I garauntee that all files and folders are removed if the user chooses to uninstall the application?

Hard to say based on your information, but a typical reason would be this: some of the executable modules is loaded in memory because some process using it is being executed at the moment of uninstallation.

There can be different reasons for that; one of them could be a bug in some application: non-terminated threads keeping the process running. If the application is a System Service, it could be kept permanently executed. So, such cases can be investigated and resolved: a bug could be fixed, the application can receive notification on the uninstallation and terminate; after all, a process can be terminated by brute force (which is no nice though), in .NET it could be done via Process.Kill (again, avoid it by all means; there are graceful methods based on sending a notification to a target process).
