Why won't sampling panels and embedded videos load consistently in my LabTutor 4 experiment?

Many windows settings can block JAVA, .NET and other software required for video, audio, and LabTutor sampling panels. Resetting all Windows and Internet Explorer privacy and security settings is an excellent place to start.  Many anti-virus programs can cause similar issues and cause panel load errors. we recommend that you turn off "on access scanning" in your antivirus software to improve performance of LabTutor 4 Client.

If resetting your Windows OS, Internet Explorer, and turning off the antivirus on access scanning does not resolve your issue, please contact your local ADInstruments tech support representative.
