Sorry, no better results.
At the first time I installed version 5.0.3 in the source filter window version 5.0.2 was shown. I deleted the filter by software an then deleted files in c\appdata\moonware and c:\programm files x86\moonware. After installing 5.0.3 again, in the source filter window v5.0.2 appears again. Wich filter is running now?
Still no connection to cam3 edimax. to delete this cam is not possible. the same for trying to edit filtersettings. Webcam7 cannot be closed, only by taskmanager. I think webcam 7 tries to connect to cam3 without success. This may be the reason for all mistakes. Once again, on my old “emergency pc” (same OS windows 10 prof) there are no mistakes with filter 4.5 (except the banner). I don’t think that there are any differences in the settings. I compared ist several times . Webcam7 is running only at one pc at the same time, so that the rtsp stream is not to share.
