In the game launcher please set Display mode to Borderless. THEN go here:

Latest supported Visual C++ Redistributable downloads

This article lists the download links for the latest versions of Visual C++ Redistributable packages. support.microsoft.com And run the x86 and x64 installers there.

IF that doesn't help, also Install ALL these Microsoft modules:

Download Microsoft Visual C++ 2010 Service Pack 1 Redistributable Package MFC Security Update from Official Microsoft Download Center

www.microsoft.com www.microsoft.com

Download Microsoft Visual C++ 2015 Redistributable Update 3 RC from Official Microsoft Download Center

www.microsoft.com www.microsoft.com

Download DirectX End-User Runtimes (June 2010) from Official Microsoft Download Center

www.microsoft.com www.microsoft.com (run dxsetup.exe after extracting from this download)

Add EU4.exe to the exceptions list of your antivirus app; ESPECIALLY if you have Windows Defender, add it to the Ransomware "Apps Allowed Through" list.

IF that doesn't help:
DXDIAG is a program you run from the Windows search box on the task bar. After running it will open a window and start collecting info with a progress bar in the lower-left corner. When it completes click the 'save all information' button and save it to a file then attach that file here.

Please attach here your Documents/Paradox Interactive/EU4/settings.txt and pdx_settings.txt .
From your Documents/Paradox Interactive/EU4/logs/ folder, attach here system.log , error.log .

As you have AMD there is no need for borderless mode, you can go back to fullScreen if you wish.

But I see numerous crashes in the AMD software there. Please try a clean reinstall of it:

- uninstall it with this tool:
https://support.amd.com/en-us/kb-articles/Pages/AMD-Clean-Uninstall-Utility.aspx - reboot
- install again by fresh download from here:
http://support.amd.com/en-us/download - reboot again

If that doesn't help, what happens if you exit the Epic app entirely and run eu4.exe directly from File EXplorer? Any Windows error show then?

Still getting those AMD crashes I see. I should have said, did you uninstall the drivers for both AMD video devices?  
13 days ago - AndrewT - Direct link
Sorry, I was mixing up another case that had two AMD video systems.

But now we see no AMD driver installed there at all under Display Devices ! If you run the game now it will try and use your Intel video device; does it run now or have the same problem as before? That will test if your issue is really to do with AMD, or is elsewhere.

Alright, you can reinstall that AMD driver now.

But we're not left with any clue where the issue is now. If you run this Windows repair tool:

Use the System File Checker tool to repair missing or corrupted system files

Describes how to use the System File Checker tool to troubleshoot missing or corrupted system files in Windows 8.1, Windows 8, Windows 7 or Windows Vista. support.microsoft.com support.microsoft.com does it find anything to fix?

Well, we are now no wiser as to what is wrong in this machine that stops our game running!

When you ran eu4.exe directly from File Explorer what did you see? Any error appear?

Are you a Steam member? If so our similar game Crusader Kings 2 is free to play there - does it run or also have this problem?

When you run eu4.exe directly Epic is not involved, nor is our launcher. The problem is elsewhere, I suspect a deep Windows issue of some sort.

Please install and run the free utility Speccy. Send its output to a text file and attach that here, thanks.

I see you have Avast, which is the most troublesome AV app for our games. Even disabled it can get in the way. If you don't want to use it I suggest you remove it completely; use both the free utilities Ccleaner and Revo Uninstaller to make sure it is 100% gone.

You also have many Windows updates which have failed or are "in progress" for over a year! You may need Windows support help in resolving that, but start by running the Windows Update app manually, see what it finds to apply. Do that and reboot.

I hope one of those helps you!

I suggest you also use Revo Uninstall to check for Avast and BitDefender - not that a firewall can cause this issue.

Assuming that doesn't help, now make a second user in Windows here, log into Windows and try the game under that.

If that too doesn't help I'm pretty much out of ammo here I'm afraid. I don't often suggest this but how do you feel about a Windows Reset?  
7 days ago - AndrewT - Direct link
Okay then, there is a problem in your standard Windows user profile. Diagnosing and fixing those is outside my experience, I'm sorry, you.would need professional Windows support help I think.

A Windows reset or reinstall would fix it for sure of course.
