DHC2 gauges not working

[Gregm8907 4]

Just wondering if I'm the only here but for some reason after a certain amount of time my DHC2 will not work properly and I will have to reinstall it. I purchased the aircraft when it first came out and used it for a while and everything worked great  but after not using it then going back and flying it again (months later) no engine gauges work and or oil/cylinder gauges. I'm experiencing the same thing right now, I reinstalled it probably about a month ago and flew it around a few times then I came back to it today and it's doing the same thing. I have not reinstalled P3D (3.4) however I am having issues with the child window problem. Is there a fix or do I just have to reinstall everytime?

During the time you weren't using it, did you install anything else?

Likely Norton has deleted/quarantined  your dll's, its advised to set your flight dim folder as an exception as well as the MVAMS folder in app data .

Reinstall the DHC2 or remove the dll's from quarantine and identify as trusted
