When installing Kollus Player, all running browsers are automatically closed.
Installation errors may occur if some browser processes are still running in the background.
Please completely close all browser processes and then try installing the player again.
Kollus Player has a feature that automatically stops playback when screen or audio capture programs are running in order to protect content copyrights.
If you see the message “Capture program detected,” please close the capture program and then play the video again.
* For PC Users
It is recommended to uninstall the capture program and reboot your computer, or completely terminate the related processes before starting the lecture.
-Even if the program is not running, playback may be blocked if its process is still active in the background.
-If you uninstall the program but do not reboot, remaining processes may still block playback.
-Some antivirus programs (e.g., Virus Chaser) may mistakenly detect the player as a malicious file and prevent playback.
In this case, temporarily disable or uninstall the antivirus program, reboot your computer, and then play the video again.
