Licensing Instructions

Standard (Royalty-Free) Licensing

In Windows, run the setup .exe file to install a license. No other actions are required.

In Linux and macOS visit the URL below to generate a Runtime License value.

After obtaining the RuntimeLicense value assign this to the RuntimeLicense property to license the application for deployment. For instance:

component.runtime_license = "<value from above>"

This provides a license to the component and your application will run without a license prompt on any machine to which it is distributed.

Note that each component instance in your code must be assigned a RuntimeLicense value.

Trial Licensing

In Windows, run the setup .exe file to install a license. No other actions are required.

In Linux and macOS visit the URL below to generate a 30-day Trial Runtime License value.

https://www.callback.com/trial/CXTJA

After obtaining the RuntimeLicense value assign this to the RuntimeLicense property to license the application for deployment. For instance:

component.runtime_license = "<value from above>"

This provides a 30-day trial license to the component and your application will run without a license prompt on any machine to which it is distributed during that time.

Note that each component instance in your code must be assigned a RuntimeLicense value.

Single Machine Licensing

In Windows, run the setup .exe file to install a license. No other actions are required.

In Linux and macOS the install-license utility is used to activate a license. Download the install-license utility from http://www.callback.com/lic/install-license.tar.gz and extract the archive. After extracting, run the install-license utility. For instance:

./install-license YOUR_PRODUCT_KEY -p CXTJA

The single machine license will be downloaded and stored in the ".callback" folder of the user's home directory (i.e. "~/.callback").

At runtime a valid license must be present in either the current directory or the ".callback" folder of the user's home directory.
