How to solve :

I know you bored from this bug, So we are here to help you! Take a deep breath and look at the explanation of your problem. We have many solutions to this problem, But we recommend you to use the first method because it is tested & true method that will 100% work for you.

Method 1

The utility Hotkey Commander should be able to show which application has claimed AltPrtScn.

You might also try the following.

Why does the Print key not work in some windows?

If you are using Windows Vista or later and have Greenshot running
without admininstrator privileges, while the currently active (i.e.
focused) program window is running with administrator privileges,
Windows’ User Account Control will not notify Greenshot that the
Print key has been pressed.

However there are some easy workarounds for this problem:

  • Run Greenshot with administrator privileges.
  • Click somewehere else (e.g. task bar) to deactivate the current window, before hitting the Print key.
  • Use Greenshot’s systray context menu to create a screen capture.

Note: Use and implement method 1 because this method fully tested our system.
Thank you 🙂
