RealtekAudio Alert

Immediately after connecting to remote computer, get message on remote (shows also on controlling):

RealtekAudioBackroundProcessClass ...

C:\Program File (x86)\TeamViewer\tv_x64.dll is either not designed to run on Windows or it contains an error. Try installing the program again ...

TeamViewer works but can't dismiss alert window (it is center of screen). After terminating session can dismiss alert window.

How to fix?  Thanks,   -JRR
