3. Problem: Invalid activation key

This problem often occurs when you type the activation t manually. It’s almost impossible to recognize I from l (uppercase i, lowercase L). The problem may be also caused by spacebar, that was accidentally typed at the beginning of the key.

Solution: Make sure that your serial number is typed properly and you have filled all required fields. The easiest way to activate our software is to copy and paste your serial number into activation window. You will avoid any mistakes that may happen during manual retyping.

4. Problem: Microphone is not being recorded / System sound are not being recorded, only microphone is

In Microphone Settings tab, select your microphone as an audio device, adjust microphone volume and audio balance.

Solution: update/reinstall video drivers. Also, make sure Action! does not run in compatibility mode.

7. Problem: Error 103

Solution: disable antivirus and reinstall Action!, add Action! files to the antivirus software whitelist

8. Problem: Action! hangs when saving longer MP4 recordings

Solution: disable antivirus software.
The problem is related with antivirus software (in our case Avast!) as it scans every newly created MP4 file and it may take a very long time if the file is big.

To solve this problem please add Action! to your antivirus software exclusion list (white-list).
