DCS World (1.5.x , 2.5.x) Crashes on start. I either get a black screen and then it crashes

It is important to check whether your video card is DirectX 11!

You can try to find your card at list here: List of DirectX 12 and DirectX 11 Compatible Video Cards

Please find more information about system requirements at the products pages: DCS World

Game crashes with an error in the dcs.log DXGI_ERROR_DEVICE_REMOVED

In most cases, it's a hardware problem with the video card or drivers.

Many hints and solutions can be found on the Internet, please Google it for - DXGI_ERROR_DEVICE_REMOVED

Some registry editing tips can be found online, in most cases, they do not help regarding DCS gameplay.

Try decreasing DCS graphic settings, set them to medium or low and then check gameplay.
Perhaps you need to reduce the number of monitors if you have multimonitor setup.
It's important to perform a Factory reset of your video driver settings - Restores all user settings and profiles to defaults.

It is very important to check the power supply unit (PSU) and the outlet.
Your power supply must have more power than indicated in the description of the video card, even if you found it on the official website of the developers. Over time, power supplies often begin to deliver less power than stated by the manufacturer. Be sure to check the operation of the DCS with another, more powerful power supply.

Moving your graphics card to a different PCI-E slot on your motherboard can help troubleshoot issues.
Also there is an option in the BIOS named Above 4G Decoding, which you can Enable in order to fix the problem.
https://biosgid.ru/parametry-bios-setup/parametry-chipseta/above-4g-decoding.html
BIOS update also can play some role here.

If you can, swapping your video card with another to check the issue can also help troubleshoot a problem.

Maybe you can find another solution, don't forget to share it with us in technical support: http://www.digitalcombatsimulator.com/en/support/

The game does not start. No error messages. HitmanPro.Alert

Perhaps you have installed on your computer package HitmanPro.Alert, checking the integrity of the browser and warning the user about dangerous banking transactions in the network. This program completely blocks the work of both the editor (Launcher.exe) and the simulator (DCS.exe). The developers of this package have been notified of the problem.

I can not remove the game from a pause.

Perhaps you have installed the program Punto Switcher.
Enter the executable files of the game in the list of exceptions or disable this program before running the simulator.

Windows 7 service pack 1

It is very important to have installed Service Pack 1 for Windows 7.
