Prepar3D V5.1– nvwgf2umx.dll crash

Post by rakesh.a »

Hi All,
I purchased p3dv5 recently, installed it in a system with the below specs
core i7 7700k
16Gb ram, 1070ti.

P3D V5 loads with the initial screen and crashes after 10 seconds.

I searched the forum and found few fixes , followed them all but still issue persists.
it's really frustrating

Tried methods
>Verified md5 checksum , its all good
> Installed as adminstrator
>Antivirus and all things turned off
> Nvidia drivers and bios upto date
> uninstalled and resinstalled
> deleted cache files and started again
> Changed GPU to gtx 1060, still same crash

Please help me, i followed all blogs but still issue persists.

As stated in many threads, roll back the nVidia driver one version.

When you roll back that driver, you will be OK.
