Possible reasons and fixes for Delta Force "SAILSDK INIT failed" error

Possible reasons

Although not officially addressed yet, the Delta Force "SAILSDK INIT failed" error appears to be an issue with the UAC (User Access Control) blocking some sort of application on your system, which it deems “illegal” while running Delta Force. It could also be due to certain missing game files or corrupted files during installation.

However, if the issue is server-related, the developers might deploy a patch within a few days to fix it.

You might also get this error if your game files somehow got corrupted or are missing due to improper installation. This can be fixed by Steam’s “Verify integrity of game files” option. Follow these steps to do so:

• Open Steam and right click on Delta Force.
• Head over to Properties.
• Go to the Installed Files tab.
• Click on Verify integrity of game files and wait for the process to end.

This should inform you and automatically fix any corruption in the game files. In case it fails to fix your installed files, or encounters missing files, you should try and reinstall the game.
