Answer 1

I thought that when you create a setup in .net it adds a uninstal option in:  control panel/(add/remove)

Answer 2

Hello.
Just so that I have said it: You should have a really good reason for doing this. I can't say I can imagine why you shouldn't ask the user to remove the program with add/remove programs.

Still, if it is urgent, here goes:

You would need to find the program by searching registry in the folders directly under

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall

1) Search for name matching the application to remove in regkey:"DisplayName"
If you find it
2a) Open a "Process" specified by regkey:"UninstallString"
2b) On successful completion: Remove the registry key (the folder containing the two values)

Remember: your program will most likely need the same priveleges you need for doing this manually (with add/remove programs).

No garanties given (you might destroy your users installation, at least in their point of view).

Again: do this only if you have to. Good luck

Hope this helps,
Gorm Braarvig.
