Trial version of GoProduce can be requested when you boot up the software for the first time:

 

Trial version of GoProduce- / GoSign ProPack can be requested in the General - About tab:


  

The trial version is only valid for 30 days. In the about window you will see how many days of your trial are still left. After that the software will stop working or in case of a ProPack the extra functionality will no longer be available.


A trial version can NOT be extended in time, nor a new trial version can be requested, nor can a trial version be reset. 

Conclusion ones a trial version on the PC has ended for a certain user (mail address) than it is no longer possible to run a triail version on that PC.
