I said "possible." You may not like it.
Background: I was disappointed that Luminar (late) 2018 and Luminar 3 refused to run on my now fairly old Lenovo G470 notebook computer. It's a =cheap= computer that I use when I travel. Oftentimes, said travel is by motorcycle, and the Lenovo fits nicely in the tank bag. With a 1.5gHz dual core Celeron processor, it is in no way fast. But it has four gigs of memory and an SSD drive, which makes all the difference in the world. I wouldn't replace that cheap notebook just because Luminar wouldn't run on it (Luminar runs fine on my six core, 5gHz, 16Gb memory equipped desktop; I just want it on my travel machine, too!).
I did research the OpenGL 3.3 matter enough to learn that it's generally not something fixable with software. I would need a new video card, which won't fit in my notebook computer. While researching this, however, I found a comment talking about virtual machines, and how all virtual machine manufacturers pretty much stopped work on OpenGL around version 2.0. I wondered how true that might be, so continued my searching. And I found a reference to OpenGL 3.3 with regards to VMWare's virtual machine.
Some may be asking, what is a "virtual machine?" Briefly, it is a logically separate computer that runs in a window on your primary machine. Once you create a virtual machine, you can install any operating system you want within (Windoze, IOS, Linux, Android, etc), specify an arbitrary amount of memory, an arbitrary amount of disk space, and etc. My preferred virtual machine provider is VirtualBox. This because in the past, Microsoft's VM capabilities have been poor, and VMWare charged for their stuff, and often quite a bit. I'm a poor boy hobbiest, not a business. But VirtualBox does =not= support OpenGL 3.3.
Times change. There are many versions of VMWare this and that available, and often expensive. But there is something called "VMWare Workstation Player" that one can download and use in trial mode. Available for Windows and Linux, at least, the licensing terms suggest that it can be used indefinitely for non-professionals, at no cost. We'll see...
And so yes... I did download VMWare Workstation Player: https://www.vmware.com/products/workstation-player/workstation-player-evaluation.html
I did proof of concept on my desktop system before moving on to my notebook computer. Seemed promising. I copied stuff to a USB memory stick and proceeded.
I first installed VMWare's Workstation player on the notebook machine. That is a "Windows 7 Ultimate" computer. It took a few reboots for VMWare to be happy with the machine's state, but it ultimately was.
I next inserted a Windows 10 installation CD into the notebook, told VMWare to create a new computer with a maximum size of 30Gb of disk space, and to install the operating system from the CD. Not too many comments required about that, but I will say that I told it to create an OS =without= an email account, and turned off all Microsoft's reporting stuff, Cortana stuff, and etc. How you would install is up to you, but you don't have to have all that crap.
I next connected a USB memory stick to the virtual machine (click on "player" and then "removable devices" to do that), and ran the Luminar 2018 installation program from the memory stick (as yet, I've little use for Luminar 3). Nothing exciting to report about that, really. It installed quickly, and reported no problems.
I then actually ran Luminar 2018. It would display an error message quite quickly and exit. It took me several launches to see that it was complaining about OpenGL 3.3 yet again. Sigh...
The default installation of VMWare does not install OpenGL 3.3 support. To add that support, you need to click on "Player" in the upper left corner of the virtual machine, then "Manage," and then "Install VMWare Tools."
Once VMWare Tools was installed, Luminar 2018 stopped complaining about the lack of OpenGL 3.3 support and ran successfully. Mind you -- it did not run quickly!!! As previously noted, the CPU on the notebook is a dual core Celeron running at 1.5gHz. No one can expect any real speed from such a processor. Much less when said processor is running both its nominal Windows 7 boot environment, and a Windows 10 virtual machine inside a window beneath that Windows 7 boot OS. Now, I can play with this a bit at runtime, if I want... Primarily, I can boost the priority of VMWare's virtual PC task in the Windows 7 task manager. I can change the affinity of the processors if need be. I can boost the VM's memory. Maybe other things as well... I dunno everything that might be possible just yet.
But the point here is that even though my cheapo notebook computer does not support OpenGL 3.3, VMWare Workstation Player 15 does. And even though Luminar on my cheapo notebook computer may require an extraordinarily long time to export a modified image (minutes), it DOES export a modified image.
Now, what VMWare Workstation Player 15 does on =your= computer is a completely separate matter. If you have an older 3gHz four core notebook with 16Gb memory that somehow doesn't support OpenGL 3.3, well then, maybe your machine will run VMWare's stuff much faster. Or if you have an older Dell running at 66mHz, VMWare's stuff (if it installs at all) may take several days to do anything. I have no way of knowing.
All of this is just an option, then. If it all seems a bit beyond your abilities, no shame in that. Messing with virtual machines and multiple operating systems on a single computer can be a bit daunting.
But again -- it works. And so it's something of an option for all you folks with older computers that don't support OpenGL 3.3, however slow or fast it might be in your case(s).
