After installing TME all DVD and BR drives in Device Manager were marked with a yellow question mark and no longer worked. It was also the error message "USB connection defective", this is happening because of an internal error. All possible attempts such devices from the corporate configuration, drivers renew etc. brought nothing. Only the restart with the System Restore at the time before the TME installation let my drives appear again. As long as this software absolutely not working and prepares only difficulty I can only max. be a star.
Of note, one may search the Internet for instructions and delete entries in the registry is well-intentioned, but for me is not an option. I expect the TME works without such actions.
