If you Flight1 GTN750 quits working, read this!

[PDX Flyer 111]

Took me a while to figure this out.  Yesterday, my Flight1 P3D GTN750 quit working.  Turns out, my Microsoft Essentials Security package for some reason started deleting the F1GTN.dll file in the P3D root directory.  Go figure?

 

So I uninstalled the GTN750, and turned off MS Essentials.  Then I went into MS Essentials and told it to exclude the "C:\Program Files (x86)\Lockheed Martin" directory.  Then I reinstalled the GTN750 package and turned back on MS Essentials.

 

Now everything works fine.

Yep. Windows defender reads the dll as a trojan and deletes it. I went back into defender in the quarantine and 'unquarantined' the dll files. Then excluded. Using Windows 10.

Let me correct myself before someone else does.  The F1GTN.dll file is in the gauges folder.  Opps.  It helps to proofread your stuff before posting.

Yup Eset Security quarrentined mine....I restored it from quarrentined and did an exclude...A-OK now.

@PDX Flyer, thanks for posting this. My GTN 750 stopped working today and I was able to fix it by following your recommendations. However, I am puzzled:  I have been flying with my GTN 750 unit for several weeks, and have used it many times without a problem. And then today it fails for the first time due to the MS Security Essentials. Why did MSE not detect and delete the .dll program before?

Because AV programs get updated all the time...

Thanks, I guess that explains it. Since I have "excluded" in MSE my P3D folder I assume this should avoid such problems in the future.

Start installing your sim outside of Program Files... you'll have far less issues down the road.
