Install OpenAL: This is a frequent cause of the game failing to launch. Many players have resolved "application not found" or silent launch failures by ensuring OpenAL is installed on their system.
Check Windows Defender & Security Software: Security programs (like Norton or Windows Defender) may block the game's data-reading/writing operations. Check your Protection History in Windows Security.
Add the game's installation folder as an exclusion in your antivirus settings.

Try disabling cloud sync for that folder or moving it to a local drive. i am an air traffic controller 4 application not found top
