I have recently had to reinstall Windows 10 and now cannot get my PMDG aircraft (777-200LR) to start.

I can load the default fighter aircraft in P3Dv4.1 without problems, but when I try to load the PMDG aircraft, P3D hangs with the Windows Task Manager showing the program using a large amount of memory but with the CPU usage at 0%.

I am sure that I have done something wrong to cause this situation but cannot imagine what that is. Any ideas would be greatly appreciated.

Do you use any anti virus software beside win defender?

Is your P3D installation located outside of the Program files (x86) folder? Have you used an up-to-date 777 installation file?

 

That much for the most common advice I've read here since now.

It's early morning in the US, so the "pros" will come across this in a few hours I think :D

my guess  its  the  dreaded  win  10 updates  again  thats  causing  your  issue,  have  to  wait  till   confirm

Hi Marc,

Windows Defender turned off. No other anti-virus software installed.

P3Dv4.1 installed in D:\Program Files\Lockheed Martin\Prepar3D v4\ and 777 freshly downloaded from PMDG.

Many thanks for your thoughts,

Cheers, Richard

Hi Peter,

Not good news if the Win 10 update could cause this situation, I agree.

If your win10 are fully upgraded this should not cause any issues.

I would suggest to open a ticket with us to check it further.

Hi Chris,

You are already investigating my ticket 0BB-21CEAA84-0411 remember, and good to hear that you are not off-air until the new year.

Cheers, Richard

When handling so many tickets each day sometimes you do not tie a post here with the ticket :)

 

Still investigating trying to see if can else to try for the simconnect errror

How many addon.xml files do you have? If it is more than 34 try removing some and starting p3d again - David Lee
