  • Error code: 1019
  • Summary: Block playback in virtual machine and dual OS environments

Symptoms​

  • Video does not play and an error code or the message "Playback is not available in a virtual environment." is displayed.
  • On dual OS tablets (devices running both Android and Windows), a popup saying "This is a jailbroken device." may appear and playback may stop.

Cause​

Kollus Player detects and blocks virtualized environments to prevent illegal recording and content leakage.

  • Virtual machine (VM) environment: Hyper-V, VMware, VirtualBox, Parallels, Oracle VM, etc. are installed and running on the PC.
  • Enterprise virtual PC (VDI) environment: Access is made through a cloud PC (e.g., MS Cloud, corporate virtual desktop environment, etc.).
  • Dual OS devices: On devices such as tablets running both Android and Windows, playback is not available when accessing via the Android environment due to security policy.

Solutions​

Fully disable the virtual environment, or use a device running a standard OS environment (genuine Windows or macOS) without any virtualization software installed.

Stop using parallels / boot camp (macOS environment)​

On macOS, if a virtualization program (such as Parallels) is running in the background, Kollus Player will be blocked.

  • Use the macOS-native player (strongly recommended): Do not use Boot Camp or a virtual machine. Instead, open a browser directly in macOS and install Kollus Player for macOS to watch content.
  • Stop Parallels services in the Windows environment: If you must use a Windows environment booted via Boot Camp or virtualization, you need to stop all background virtualization services.
    1. Press [Windows]+[R] on your keyboard to open the Run dialog, type services.msc, and press [Enter].
    2. In the services list, find Parallels-related services (3 items), right-click each one, and change the startup type to [Disabled] in [Properties].
    3. In [Task Manager] > [Startup Apps] (or Startup) tab, also set any Parallels services to [Disabled].
    4. Restart the system and try playing the video again.

Check dual OS tablet environment​

This applies to devices with both Android and Windows installed simultaneously.

  • Boot into Windows: Boot the device into the Windows operating system environment and then play the video. (Playback may be possible in the Windows environment.)
  • Use a different device: If playback is not possible even in the Windows environment, or if you must use the Android environment, use another smartphone or tablet PC without a virtualization architecture.
