Error when trying to capture on Windows: "An error occurred while capturing the screen: process is not open for write"
This error can occur if you have Clarify 1 installed and the Clarify 1 status menu helper is running in the system tray. Follow the instructions for turning it off.
Check to see if you've assigned the shortcut key to capture screenshots in Clarify to a key combination that is in use by another application on your computer. If you have, change the shortcut key. You may need to restart the computer.
If you don't have the Clarify 1 status menu helper running then you can try reinstalling Clarify 2. This has resolved the issue for some users.
