Transfer license

Licenses are linked to a machine when activated. As such it is necessary to return a license if you wish to activate it on another machine.

You can automatically change the license in use by going to the About window and clicking on Change License. This will automatically return the current license, activate the new license, and restart SolidQueue. You can open the About window by clicking on the license icon in the status bar, or going to Menu > About.

Alternatively you can manage licenses in the Solid Solutions Licensing application that was installed alongside SolidQueue. Launch Solid Solutions Licensing on your machine to manage your license (it will have been installed alongside SolidQueue).

The licenses on your machine will be displayed. You can click View on a license, or double click it to view more information about the license. You can return a license by clicking on Return. SolidQueue will prompt you for a license key when you next launch it.

Licensing Details

Refresh license

Typically it should not be necessary to manually Refresh a license, however it may be necessary if a license has been modified and those changes are not reflected on your machine. For example, if you have upgraded a Standard license to a Professional license then a manual Refresh will be necessary to force the license to be updated.

To Refresh the license first launch Solid Solutions Licensing on your machine, then click View on the SolidQueue license followed by Refresh on the license details window.


Licenses are linked to a machine using a machine identifier. This identifier can change in certain circumstances, typically a hardware change.

If the machine identified changes then the license will no longer be considered active on your machine and attempting to re-activate the license will result in an error message stating the activation count has been exceeded. Please contact [email protected] for assistance in such cases.
