  3. Start the copy you repaired

    Start MTA from the installation you just repaired. If the warning is still there, tell MTA support the exact message and whether the installer finished.

    Careful: Do not use registry fixes copied from forum cases that are about something else.

Still not fixed? Copy the whole message, not only the code, and check your log in the Fix tool. It is read on your own computer.
