Diablo 4, the highly anticipated action role-playing game, has captured the hearts of gamers worldwide. But some players have run into a frustrating problem: the “unable to open a critical file” error.
This error stops them from starting up and enjoying the Game, especially if they are using the Xbox Game Pass. Fear not, as there are solutions to overcome this obstacle.
The Root Cause
The “unable to open a critical file” error in Diablo 4 is primarily related to pending game updates. The way Microsoft updates and shares games through the Xbox Game Pass is different from other platforms. This difference can sometimes lead to conflicts, resulting in the inability to open critical files required for the game to run smoothly.
Solution 1: Update Through Battle.net
One effective solution is to update Diablo 4 through the Battle.net launcher. Follow these steps:
- Close both the Xbox app and the Battle.net launcher.
- Reopen only the Battle.net launcher.
- Navigate to the Diablo 4 section and check for any available updates.
- If updates are available, initiate the download process.
- Once the updates are installed, relaunch the Xbox app.
- By updating Diablo 4 through Battle.net, you ensure that both platforms recognize the latest game files, potentially resolving the critical file issue.
Solution 2: Delete and Reinstall Battle.net Files
If the first solution does not work, try deleting the Battle.net files and reinstalling them. Here’s how:
- Close all Battle.net-related processes using the Task Manager.
- Press the Windows Key + R, type “C:\ProgramData”, and press Enter.
- Locate the Battle.net folder and delete it.
- Reopen the Battle.net launcher and check for Diablo 4 updates.
- Install any available updates.
- Deleting the Battle.net folder removes any potentially corrupt files that could be causing the issue, allowing you to start fresh with the latest game files.
