What to know before you begin
Wrong operating-system assets, incomplete archives, missing runtimes or renderer problems are common starting checks. Use the project's release notes rather than random DLL downloads. The project offers several scanning modes and the current version may place controls differently in Krokiet versus the older GTK GUI. Follow the meaning of the option you see, not just a screenshot from a different release.
For Windows, verify that your chosen folder is accessible and that the correct graphical frontend is running. The recommended approach starts with a small test set, especially when an action could rename, move, delete or link files.
Step-by-step: Why won't a Czkawka or Krokiet file launch?
- Verify the filename is a Windows GUI asset.
- If ZIP, extract the entire archive before opening the program.
- Read Windows Event Viewer or application logs if the process exits.
- Try an alternate supported build from the same release.
Important limitation
How to verify the result
Verify the app launches cleanly twice and can scan a test folder. A scan's estimated savings or the presence of a matching group does not by itself establish which copy should be discarded.
If the procedure does not match your screen, inspect the project's own FAQ and troubleshooting notes and identify the exact release and frontend first.
