Well, I've just downloaded and installed the latest update to Capture 2023 (for which I am licensed) and the Quartet PC is there...
But, if you are using the student edition then I expect you have read the limitations - if not then they say...
Capture 2023 Student Edition
The Student Edition of Capture is a free version of Capture that may be used for any purpose, educational or not.
Feature-wise it is based on the Solo Edition, with the following differences:
Unlimited number of DMX universes.
Reduced amount of trusses and fixtures in the library. The full list of fixtures is available here.
Motion (DMX movers, DMX rotators and motion constructs) and effects (CO2, fire and water jets) are not available.
Opens and saves Student Edition project files only.
Does not export Capture Presentation files.
All console connectivity options except MA-Net3 are present and fully functional.
and will have checked out the link to available fixtures which, sadly, does not include your specific models.
Are you a student at an establishment which has an education licence for Capture? If so then speak to your tutor as they may be able to help. If no then, for the purposes of trying out effects and seeing roughly how your programming will look then you will need to use the closest available fixtures from the reduced set available in the student edition.
Free editions of software will always have some limitations - nobody would pay for a licence if they didn't - and Capture student appears to have what you need to set students a design task and for them to complete the assignment.
