Hi Clive, grab a coffee - here comes a long message.
It looks like Roxio Burn didn't install, for some reason. Perhaps you installed it over the top of an earlier version?? I haven't come across this before, and I don't know why it didn't install.
Best idea I can think of at the moment is to try and Repair it. You only get a limited number of installs allowed, (20 for NXT 7) so completely uninstalling it and then reinstalling is the final option. A Repair doesn't take away any of your limited number of installs.
This process looks more complicated than it really is, and I don't know how much help Roxio Support might give you, so I'm preparing a walk-through which I hope will help. Please read through it until you understand what to do, before you actually start it. Ask questions if you need to. Try Roxio Support if you want, I'm just an enthusiastic user and not a Roxio employee, so I won't be offended.
You didn't say what Operating System you're using, so I'll assume it's Windows 10. Please tell me immediately if it's something else.
The installer records where it got the Roxio programs to install, and if you ask for a Repair, it expects the install package to be in the same place where it was so it can get the files it needs. You will need to put the Roxio installer files wherever they were at install time - DVD back in the drive, or file folder back where it was - so the installer can find them again for the repair. PLEASE DO THAT NOW. Okay, ready? Let's go.
-go to Start, click on the Settings cog, and type "control panel", then click on "control panel"
-click "Programs and Features" and look for "Roxio Creator NXT Pro 7". Click on that and you should see "Uninstall/Change" appear on the line somewhere above it.
-Click on that and it should start the Roxio Setup program.
-Click Next, and you should see this screen. Click Repair.
-You should then see this screen. Click Repair again
There are no installation settings to change at this point, so click Repair and the process should start. Hopefully it will run right through, and at the end you will have the program suite reinstalled - including the missing Roxio Burn module. Whee! Some celebration! It's done!
But wait, if it doesn't just run to the end there may be more.
If your installer folder wasn't exactly where it originally was, the installer will get lost at this point, and you will see messages like this:
Don't Panic! At this point you have to look down the whole length of the "Source" line and work out what file the installer is looking for. Browse to where that file is, and tell the installer. Repeat this 6 or 8 times until all the important bits have been found, and the reinstall is finished.
Now, if the repair worked that's fine! If it didn't work, my next suggestion is to completely uninstall the software, clean up any remnants you can find, and then reinstall from scratch taking a careful note of things as they happen, and especially any error messages. Any questions?
