Q++Studio is licensed on a yearly basis and you will need to update your license files once a year.

the stage of the update when the license files have been updated, even if you choose to cancel the update
Whenever your renewal has been processed, an updater to your license files will be available online.
To update your Q++License Files:
1.Launch the XV4 Q++Studio main program updater.
2.During the initialization of the updater, the most recent license files will be automatically downloaded and installed.
3.Then, as soon as you reach the stage where you choose an Update type (see image on the right), you can click the Cancel button to abort the update, or you can choose to proceed with the update (in either case, your license files will have been updated).
License updates during the year
You will also need to get updated license files, whenever you make major changes to the hardware configuration of your workstation (ie. reformat disk c:\, change network card, etc...). In that case you should follow steps 7 and 8 of the workstation installation instructions again, before following the above instructions.
If you get a message that your Q++Studio license is damaged (as opposed to needing to be updated), then please follow the instructions here.
