Installing the Mixbus license

Our licensing method has changed as of version 5.3 please pay careful attention to the instructions below


At startup, Mixbus checks to see if a license is installed. If no license has been installed, you will see the following “UNLICENSED” dialog:

After purchasing Mixbus you will receive, both on the final page of the checkout process, and in your email, a cryptographically signed license generated by us. This is the license that unlocks the full program. To use this license:

  1. Highlight the license text from begging to end and then copy it.
  2. Click the Paste button in the dialog.
  3. Mixbus will verify the license’s signature and then allow you to apply the license to the program.
  4. Click the Apply button.


Using Mixbus without a license file:  If you choose to use Mixbus without a license file ("demo mode"), it will work normally except for an periodic quiet noise ("hiss").  This prevents you from publishing complete commercial-quality mixes, but otherwise has no effect on the operation or sound of Mixbus.  Additionally, the Mixbus product page will be displayed in your web browser when Mixbus is launched.  You can fully license Mixbus any time by downloading the license file to your system.  No re-install of Mixbus is required.

Installing the license file manually:  The Harrison "license file" for each of our products is a simple text file.  You can click to download the file, and then save the file to your HOME folder.  For more details, see this article.

Keeping a backup of your license file(s):  The Harrison "license file" for each of our products is a simple text file that may be freely copied, moved, and backed-up for your convenience.

License Usage:  You may install your license file(s) on all of your computers, as long as you are the only user.  The license file has your name encrypted in it, so you should not share it with others.

License Availability: The license text never expires, however the link to download your license file is only valid for seven days. If you need to  have it resent, please write our support email ( mixbus@harrisonconsoles.com ) and we can send you the licenses for all of your products in a timely manner.

License File Name: Each of our products ( Mixbus, Mixbus32C, and various plugins ) have a different license file associated with them.  For example, the license file for mixbus is called "license_key_harrison_mixbusX.txt" and it should be saved in your HOME folder, where Mixbus will find the file and use it.  It is important that the filename is exactly correct.  If you download a file more than once, your browser might append a "(1)" or "-1"  to the duplicated file.  In this case, you should rename the file to remove the extra characters.

Displaying your HOME folder with your available license files:   In Window->License Manager,  you can click "Show License Folder" to show your HOME folder.  You don't have to use the "License folder" button to find your HOME folder, though.  You can click Go->Home in Finder (Mac OSX), or click your user-name in the Start Menu (Windows).

Installing the License to a different folder:  If you don't want the license files in your HOME folder, Mixbus will also look for the files in these locations:

On MacOS,Mixbus searches the following locations (first found is used):

  • $HOME/Library/Application Support/harrisonconsoles/
  • $HOME/.
  • /usr/local/share/ (intended for multi-user institution-wide licenses)


On Windows, Mixbus searches the following locations (first found is used)

  • $HOMEDRIVE$HOMEPATH
  • %localappdata%
  • $USERPROFILE

  • $HOME/.
  • $XDG_CONFIG_HOME/harrisonconsoles/
  • $HOME/.config/harrisonconsoles/
  • /usr/local/share/ (intended for multi-user institution-wide licenses)
