Cloud Compare Wont open

[MarcdWright]

I just found out about cloud compare and downloaded 2.13.2 . But it will not open at all it loads for second but nothing pops up and my task manager wont show it either.

Hum, we've had some issues with ATI cards in the past, but if it's a rather recent one, it should be the problem.

Have you tried to update your graphic card driver just in case?

(on Intel laptops, it's generally possible to switch to the integrated chipset for display, and it's a way to test that the issue comes or not from the graphic card... however in your case, I'm not sure there's such a thing on a Ryzen processor).

I made sure everything was up to date but it continues to not open. I saw it pop up in the "background processes" for half a second but that's as much as I get.

Yes, sadly that's very typical of Qt failing or refusing to start with an 'unsupported' graphic adapter...

Had the same issue. Not just with Cloud Compare but with Blender as well. It was the same fix for both of them. I checked for it in the task manager as well. I had the same symptom as above: Cloud compare opened for a split seccond as a process but before it could render anything on screen the process terminated.
The reason was a missing OpenGL dll.

To fix it, go to: TBC
Find the current version. Download, unzip, find the Cloud Compare installation directory (for me it was:
C:\Program Files\CloudCompare)
Paste in "opengl32.dll"
Try again, should work now.

Before we agree to post your link above, I'd like to know the origin of this DLL.

Swapping a DLL can be very dangerous, and give access to attackers.
