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.

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).

9. Problem: Action! crashes when recording Call of Duty WWII

The game crashes when Action! tries to connect to it.
Temporary workaround to this problem in three steps:
– add the game to the excluded list
– run the game in borderless fullscreen mode
– set Action! in Active Screen recording mode.

To add a game to excluded list open notepad and type:

Save the file as an exclude.txt and put it in Action! folder.
Now start Action! and select Active Screen recording mode (one for
desktop recording).
Run Call of Duty: WWII and go to Settings -> Graphics and Display Mode
set to “Windowed (no border)” or “Windowed (no border extend)”.
Action! HUD should show up in the game and you are now ready to record/stream
your video.

10. Destiny 2 –  instructions for safe and high-performance Destiny 2 game recording with Action!

To make sure that Action! doesn’t hook up to the game you can add destiny2.exe to the excluded list.

To do that open notepad and type: destiny2.exe

  • I have a strange problem. When I’m streaming to YouTube using Mirillis Action Recorder the stream is completely interrupted by loading. For the entirety of the video it’s loading, when the screen moves at all, loading. When the stream catches up to me, loading. I followed the regular steps to streaming but for some reason it just doesn’t seem to want to work.
