We can't update any library or executable that is currently in use. For the updater executable we solve this problem by copying the updater before using it to a temporary directory. + +== Update procedure == + +The updater executable is run two times. In a first run, the current installation is copied to a "update" directory and the update is applied in this "update" directory. During the next run, a replacement request is executed. The replacement request removes the old installation directoy and replaces it with the content of the "update" directory. + +=== User profile in the installation directory === + +The archive based installations have the user profile by default inside of the installation directory.
