0x00000538 – Error_Invalid_Acl – the Access Control List (Acl) Structure Is Invalid

The error code 0x00000538, known as Error_Invalid_Acl, means there's a problem with the Access Control List (ACL) that controls who can access files and resources on a computer.

This can happen if the ACL is damaged, permissions are set incorrectly, or software isn't compatible. When this happens, you might not be able to open files, your computer might crash, or you could see random error messages.

To fix it, you can reset permissions using Command Prompt or check for system file problems. Understanding this error is important to keep your computer safe and running well.
