"Could not mark image file for add" when changing Icon in ProjectSettings

Hi,

I’m trying to set a customized Icon in the Project Settings.
Whenever I choose my desired Icon from the Explorer I get an Error (Image bottom right).

First I tought that I made a mistake when creating my Icon, but I have also tried it with a copy the Default.ico from the Engine folder, and am getting the same error.

Any Ideas?

I wonder if you are also using git integration? I had this same problem this morning. In order to get around it, I had to turn off source control integration. I was then able to set the icons. Of course, I manually tracked my icons in git and re-enabled source control integration right afterward!

I am facing the same problem. Using Perforce and even after manually checking out the image file in Perforce for example, the issue still remains.

Bingo. That was the problem. One would assume that’s a bug. After disabling source control from the Unreal Engine editor, it worked.

Had the same issue with git. It’s definitely a bug.
