--------------------------------------
If you want to move your license to a different system, please uninstall the solution from your old system (V. Uninstall solution) and install the solution again on your new system (II. Install solution).
This is not possible if you use a trial key.

VII. Offline license validation
-------------------------------
If your SharePoint Server is located behind a proxy or is not permitted to access our online key validation service you will need to perform an offline validation to successfully complete the setup and activate the solution.
If the setup can't connect to the key validation service (http://keyvalidation.sapiens.at/validate.asmx) it will create a file named unvalidatedSurety...xml in the setup folder. 
Upload this file to the manual validation page http://keyvalidation.sapiens.at/manualvalidation.aspx to perform an offline validation and download the validated surety file back to the setup folder and run the setup again.

VIII. Manually remove license usage
-----------------------------------
If your SharePoint Server is located behind a proxy or is not permitted to access our online key validation service you will need to remove the license usage manually to be able to use the license key again on a different system.
If the setup can't connect to the key validation service (http://keyvalidation.sapiens.at/validate.asmx) it will create a file named uninstallSurety...xml in the setup folder. 
Upload this file to http://keyvalidation.sapiens.at/manualuninstall.aspx to remove the license usage. Now the license key can be used on a different system.
