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.
- Right-click the optimizerDuck application file
- Select "Run as administrator"
TIP
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:
- Delete the downloaded file
- Re-download optimizerDuck from the download page
- 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:
- Open File Explorer
- Right-click your C: drive → Properties
- 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:
- Visit Microsoft .NET Downloads
- Download and install the latest .NET Desktop Runtime
- Restart your computer and try again
