How do I fix a hotkey registration error?
The shortcut may already be assigned to Windows or another screenshot app.
How to do it on Windows
The shortcut may already be assigned to Windows or another screenshot app. Before changing capture or export settings, save any important existing work and check the Windows notification area for a running Greenshot process.
- Step 1. Record the conflicting keyboard combination from the error or preferences.
- Step 2. Quit duplicate screenshot utilities, including overlay tools if appropriate.
- Step 3. Assign an unused shortcut and restart Greenshot to confirm.
How to verify the result
The hotkey should work without conflict messages. Check the actual image file or open capture result instead of relying only on a successful shortcut animation. If the expected output is missing, repeat the task with a known local folder and the tray-menu command.
Common limitation or mistake
For repeatable troubleshooting, record your Windows version, Greenshot release, capture mode and chosen destination. Changing one setting at a time makes it easier to identify which adjustment helped.
