I'm only flying on Aerosoft A321, but I think this may be an error - not thinking of the aircraft (general  problem??):.

The entire error message is:

Faulting application name: Prepar3D.exe, version: 5.3.17.28160, time stamp: 0x61e6ab02
Faulting module name: terrain.dll, version: 5.3.17.28160, time stamp: 0x61e6aa88
Exception code: 0xc0000005
Fault offset: 0x00000000000df08f
Faulting process ID: 0x32d8
Faulting application start time: 0x01d8622ab1dfbeb5
Faulting application path: C:\Prepar3D v5\Prepar3D.exe
Faulting module path: C:\Prepar3D v5\terrain.dll
Report ID: 6372944f-3a99-42a9-95fe-e90800888dd7
Faulting package full name:

What could possibly be the problem? It appears to be a problem with terrain.dll, but I'm not an expert on this.
Please help!

Check for the AVSIM CTD guide, it should point you in the right direction. Off the top of my head I would check that Tessellation isn't higher than your PC can handle. Worst case, delete the terrain.cfg file in your "C:\ProgramData\Lockheed Martin\Prepar3d V5" folder. Then use Orbx central to verify, layer and sync your orbx sceneries to the simulator. There are a few threads around on doing that. 

Have you gotten an error in the same .dll more than once?  

A C0000005 exception is a memory access violation, and could be caused by a large number of things, and not necessarily in the terrain module.  That just happens to be what was executing when the exception got thrown.  If it's a one-off occurrence, it's really not even worth trying to track it down.  If it happens a lot, but in different modules, then an unstable system (a bad overclock, an iffy DIMM, a weak PSU) a misbehaving add-on or a corrupt texture or other data file, or a graphics/driver problem are all among the possible causes.

If you do get multiple crashes in the terrain.dll, then the first thing I'd look at is anything recently-added that might include a terrain element--mesh, scenery etc. 

 

So looking at both replies, my laptop is not good enough. It is a games laptop, but I'm worried about the spec.. it's not really a new laptop.

What are the specs Gaz?

As a first step to resolving CTD's I always first delete the compiled shader Cache and the Scenery index .dat files

Both will rebuild with nice fresh and clean values.

How would you do this?

Just for info, this is always execrated before my flights:

 @echo off
echo before LastDownloaded
del /q %appdata%\HiFi\ASP3D\Weather\LastDownloaded.Wx
echo LastDownloaded.Wx deleted

echo Clearing of Shaders
del /q "C:\Users\mail\AppData\Local\Lockheed Martin\Prepar3D v5\Shaders\*.*"
echo shaders emptied

pause

Nifty, you could apply a similar script to clear the scenery indexes.

They are located in "C:\ProgramData\Lockheed Martin\Prepar3D v5\SceneryIndexes_x64\"

I typicaly don't clear them all the time though, just if I start to get unexplained crashes.

Otherwise yeah, go for it.

@rogan

Sorry if I got the wrong name there.

I haven't had a chance to check out your recommendation, but I will find time to do it and get back to you

You may also want to make a backup of your prepar3d.cfg file and delete it and let P3D regenerate it (you will need to reset your settings).

Best of luck!

so far, so good!
