Installer: files in use

[stephtr]

When updating a running installation the setup doesn't stop the running executable and displays a "Files in Use - Try Again, Continue, Exit Installation" dialog instead.

Workaround: Terminate FixSurfaceKeyboard using task management or task manager, or simply press "Continue" which should schedule the update for the next reboot.

The exe file and setup project have incrementing version numbers, the setup project has also "RemovePreviousVersions" set, therefore it isn't quite clear to me why the setup doesn't terminate the task.

The issue is partially solved by moving to WiX, now it just displays a dialog through which one can kill the running exe file. Not showing that dialog would be still nicer.
