Below is a comprehensive, long-form troubleshooting and analysis article designed to help you resolve the “Application Not Found” and “Top” related errors. If you are an aviation enthusiast or a retro gamer, this guide is for you.

✅ Antivirus / Windows Defender

Restore quarantined files and add the game folder as an exclusion.

Step 1: Verify You Have Extracted the Game

Symptom: You double-click a file inside a .zip or .7z folder and see "application not found."

Fix:

• Right-click the downloaded ATC4 archive (e.g., ATC4_RJTT.zip).
• Select Extract All (Windows) or use 7-Zip/WinRAR.
• Extract to a simple path like C:\Games\ATC4.
• Do not extract to C:\Program Files (Windows security restrictions can block old games).
• After extraction, navigate to the extracted folder and try launching ATC4.exe directly (not via shortcut).

✅ Check shortcut properties

Right-click shortcut → Properties → Target should point to the correct .exe
Start in should be the game folder (not a subfolder like \data)

Step 4: If you see “Application Not Found” for an existing announcement

1. Clear your browser cache or use incognito mode.
2. Log out of USAJOBS, log back in.
3. Go directly to “My Applications” – not a saved link.
4. Search for the announcement number on the FAA’s internal careers site (not just USAJOBS).

If the announcement has truly expired, wait for the next bid. The FAA hires twice yearly.

2. Missing or Renamed Executable

The core game file (ATC4.exe or AX.exe) has been deleted by antivirus software, moved, or renamed. The launcher is looking for a specific name but cannot find it.
