App Won't Open

The app crashes or fails to launch

If optimizerDuck fails to start, try the following solutions.

Check system requirements

Make sure your system meets the minimum requirements:

Requirement	Details
OS	Windows 10 or Windows 11 (64-bit)
Permissions	Administrator privileges required
Disk space	At least 100 MB free on your system drive (usually C:)

Run as Administrator

optimizerDuck requires Administrator privileges to apply system optimizations.

1. Right-click the optimizerDuck application file
2. Select "Run as administrator"

Set always run as Admin

If you always want to run optimizerDuck as Administrator, right-click the file → Properties → Compatibility tab → check "Run this program as an administrator" → OK.

Check for corrupted download

Your download may have been interrupted or corrupted:

1. Delete the downloaded file
2. Re-download optimizerDuck from the download page
3. Try running the newly downloaded file

Check disk space

If your system drive (C:) is nearly full, apps may fail to launch or behave unexpectedly:

1. Open File Explorer
2. Right-click your C: drive → Properties
3. Check the available free space

If space is low, try:

• Emptying the Recycle Bin
• Running Disk Cleanup (search for it in the Start menu)
• Moving large files to another drive

Check for missing dependencies

In rare cases, optimizerDuck may require the .NET Runtime to be installed. If you see an error about missing frameworks:

1. Visit Microsoft .NET Downloads
2. Download and install the latest .NET Desktop Runtime (not just the Console Runtime)
3. Restart your computer and try again

Run a System File Check

If the app crashes immediately without any error message, your system files may be corrupted:

1. Open Command Prompt as Administrator
2. Run:

   sfc /scannow

3. Wait for the scan to complete (this may take 15-30 minutes)
4. If issues are found, restart your computer and try launching optimizerDuck again

Check Windows Event Viewer

If optimizerDuck still won't open, the Windows Event Viewer may contain helpful error details:

1. Press Win + R, type eventvwr.msc, and press Enter
2. Go to Windows Logs → Application
3. Look for error entries related to optimizerDuck or .NET Runtime
4. The error details can help identify the root cause
