Hi, Turned off Windows Defender and told Windows Defender to no look at my EFB installation folder. After that I rebooted my system and ran the DataProvider and I still got the same error message after exiting the DataProvider. This time while testing I only ran the DataProvider and nothing else, I also tried it once with the DisplayUnit but I still got the same error. Normally when I am simming I have P3D v3.1 with all my addons (ORBX, REX 4 + Soft Clouds, PMDG 777, OPUS etc.) and probably also Google Chrome open by the time I close the DataProvider. But everything is working while I am using the EFB (I think), its just when I close the DataProvider I get that error message. Javier Frazier
