Hi everyone

i already made a Post about my problem, and it ended in a refund. after a while i said to myself that i would like to try it one more time, and so i buyed P3d v4 again.

My Problem:
When i start P3D the splash screen comes up and i see the loading bar (sometimes) loading scenery and other stuff. P3D is also visible in the Task Manager at that moment. After about 10 Seconds the screen dissapears and P3D also dissapears from the Task manager without any warning. 

i tried

- Multiple reinstalls (even new downloads and hash verfication of the entire P3D file).
- Repairs with the P3d Setup programm
- unplugging all usb devices
- checking that i have net.framework and all graphics and windows drivers up to date
- everything thats on the debugging thread.
- deleting cfg. file and others.

as you can see this is going to be pretty tricky. at the moment the P3d is freshly installed an untouched so im ready for your advices.

My System:

Nvidia GTX1070,Intel I7 6700HQ, 16GB RAM, Win 10 64bit



thanks in advance and greetings from switzerland

First try running as Administrator, just to get that out of the way - then

If this is a CLEAN install with NO addons then it must be something else on your system. Try doing a clean boot

 and see if it runs.

If it does then selectively enable/disable all your non critical running processes  one at a time and retry.

Also, are there any messages in the event viewer about what might have caused the crash?

Until you get it to load do not make any changes to the p3d.cfg file or add any other software.

thanks Vic ! 

i will try the clean boot tommorrow as it is pretty late in switzerland... when i start P3D i get these errors in the event viewer.

i dont know if this one is related, its a second error (not application fault like above) that seems to occur when i start P3D:

Unable to start a DCOM Server: {9AA46009-3CE0-458A-A354-715610A075E6} as Nicht verfügbar/Nicht verfügbar. The error:
"740"
Happened while starting this command:

No, you can ignore the DCOM message. The api.dll usually means something with the USB system. Another thing you might try - see if there are any updated USB drivers for your system online. Download and install them. possibly prior to that you might just go into device manager and uninstall all your usb devices. Shut down and restart and et windows reinstall them.  See if that helps.

thanks, i hope that we are getting closer ! I will have to go to work now, so i will try most of the things you mentioned later...one thing i did try, was to unplugg all USB devices when my Computer was turned off. Then i restartet with nothig attached... and somehow P3D took much longer to get to the loading bar on the splash screen. I did get the same error, but maybe this menas something. the whole time until it crashed was like 10 times longer than usually.

 

thanks

When all else fails I reinstall windows and start fresh! FYI Lockheed Martin will not refund you a second time. The refund policy is limited to 1 refund only.

if really nothing goes i will do that, but for now i wanna try some more. I am aware of the refund policy.. but i said to myself that i will anyway want to use p3d if not on dis computer then on another so im ok with that.

You WILL get it sorted. Just a process of elimination and very frustrating.

Vic, You could be onto something here with the USB drivers alright,  This specific error api.dll did cause an Issue on the first launch of v4 with USB controls

Stephane's,  did you try Vic's suggestion of Manually updating your USB drivers ?   Also did you try my last suggestion  (As a process of elimination)  ?

Hi Poppet, 

the things i did without success

- Create new User Account with admin rights

- Downloaded the latest USB driver and found out that i already have it, so i just clicked on "repair".

 

thanks

Listen brother.  do what they tell you. You need to start from scratch.  Not just creating another account on the Pc.  From scratch.  That means getting a windows cd or a USB stick and formatting your PC.  Back up what you have on the PC and wipe the pc start again.

Do you mind doing that?? It means wiping the pc.

A simple yes or no answer will do here

actually this is not what they told me.. i think im doing exactly as ive been told. Poppet told me to create a new account on the P3D forums, thats why i did it. A fresh windows install will only be my last option.

Same thing just started happening to me as well. I did a complete wipe of the install, and it started back up again. I am assuming there is an addon compatibility issue, which is odd because I am only using official v4 installers. Very frustrating. 

New ndivia drivers??  

Do you have v3 on your pc aswell?
