Hello,
Thank you for the clarification.
Could you please try enabling the
Use legacy capture mode feature in the
Host Settings -> Other tab and see if this helps to resolve the issue?
After enabling the feature please restart your Host in order for the changed to be applied.
In addition, please double-check if the
rfusclient.exe file is present in the Host installation folder
C:\Program Files (x86)\Remote Utilities - Host\* as the issue might be occurring in case if rfusclient.exe was accidentally removed (for example, by some antivirus software). In case if the file was indeed removed from the folder, then please try re-installing Host and make sure to add the Host installation folder to the antivirus exception list as described
here.
Last but not least please make sure to update your RU installation to the latest version
7.0.2.0 - it's available for download on
this page or via
Self-Update feature. When updating please make sure to update both Host and Viewer to the same version in order to avoid the version mismatch.
Hope that helps.
