Help please

Check your log.txt (it's in your X-Plane 12 folder) and see if tells you more info. Your message does not say if you have been able to run XP12 in the past, or whether you're trying it out for the first time. It could be caused by an outdated graphics card driver, or a totally incompatible graphics card. Either way, more information is needed if you want more help.

that's what he writes. before that, everything was fine, it's not the first time I've launched it. what could have happened?

[Echo Kilo]

This sounds very similar to your problem:

To fix it, you need to reinstall your Nvidia drivers.

Re-Install the Nvidia driver. There is a known bug with Nvidia's installer that just deletes the Vulkan runtime altogether. Nothing X-Plane can do about that, that's driver territory.

Downgrade Nvidia Game Experience to version 527

I tried to downgrade and reinstall but it wont work. Other ideas?

[pozeluk_old]

I completely demolished the RADEON software (drivers and all that), reinstalled it from the official server and everything went well

[hiker44]

I tried new Radeon drivers too, no luck.
