Hi Macboy, did you determine which graphics hardware you have in your laptop? I'm still fully confident we can get you up and running but I'm going to have to be up-front in saying that it appears as though you may have downloaded and installed a driver for your laptop other than the one for your graphics hardware. Can you tell me which driver(s) you installed?
EDIT: Before you follow through on the instructions I provided below, the black/console window that you snapped a picture of provides more information about your graphics hardware that it detects, and other useful information that will help me solve the problem. Scroll to the top of the window to the beginning of the output that PixelCNC generates there, and it should mention a GL_VENDOR and GL_VERSION. You don't actually have to take a screenshot, just telling me what it says there would be useful, but it sounds like you'll need to do a bit more work getting your system properly configured.
You mentioned BIOS updates, which are not related to graphics drivers, and should've only installed if you made it a point to install all of the drivers that the Dell page auto-detected that your system needs - which should've included the graphics hardware driver. Otherwise, if you made it a point to manually seek out and install the graphics driver by itself then BIOS updates would've only installed if you had accidentally mistaken a driver with "Intel" in the name as being the graphics driver. There are multiple drivers for your system with 'Intel' in the name which are not actually graphics hardware drivers. The Intel graphics drivers are distinguished from other various Intel drivers by the 'HD' or 'GMA' suffix that follows 'Intel' in their name. This is because your system has an Intel CPU and other Intel components, and therefore uses multiple Intel provided drivers.
Apologies if I am completely underestimating your aptitude, ability, or awareness, and you actually managed to install the proper graphics driver. I cannot stress enough that am not trying to be insulting or condescending by assuming a mistake, I am just going on the clues and evidence I have available to me, and I recognize that there's a distinct possibility that you may have simply installed a motherboard/BIOS Intel driver instead of the graphics driver, purely by mistake. There's also the possibility that because you have Windows 10 installed on an older laptop that is no longer supported by Dell that the automatic driver detector simply did not provide a graphics driver in the list of drivers it displayed to you - because there are no Windows 10 drivers for your laptop. If that's the case then you will simply need to manually install an older driver, which will work fine regardless. Likely a 32-bit Windows 7 driver, if your system actually is 32-bit as you mentioned before, as Windows 7 was the last OS that Dell supported for that laptop, and thus provided drivers for.
I can assure you that whether your laptop has an Intel 'HD'/'GMA' or an Nvidia graphics processor that it will run PixelCNC - and be able to access long-existing OpenGL functions such as glActiveTexture which have been standard for nearly two decades. So something must be preventing your machine's graphics capabilities from being utilized, and in my experience the wrong drivers (or missing drivers) are the culprit. Also, the link to the glActiveTexture bug page you found was actually a discussion between programmers about writing software that utilizes the function, and erratic behavior one programmer was experiencing, which is unrelated to the problem you're experiencing. "glActiveTexture" is one of many graphics functions that PixelCNC is unable to utilize from your hardware, and is only the very first one that it attempts to confirm accessibility for. A failure to access the function automatically prevents PixelCNC from attempting to access the rest of the graphics functions that it needs so that users are not bombarded by a barrage of error boxes for all of the missing graphics functions. The fact that PixelCNC errors out with "glActiveTexture" as being what the error specifies is purely incidental, and not specific to the glActiveTexture function itself. The problem lies in the graphics hardware not being properly configured for software to be able to access, which just means we need to make sure it's configured properly ;)
We can get to the bottom of the graphics hardware situation directly by seeing what Windows says about it. To do that you can look for yourself to see what graphics hardware you have, and what driver is currently installed for it - which I imagine is the default "Microsoft" provided driver that only grants very basic minimal functionality. It's provided as a last-resort graphics driver when the correct driver is not found. Without this default fall back driver Windows wouldn't be visible on the screen at all when the proper driver can't be located, so Microsoft provides it for convenience purposes. The problem is that it doesn't implement the advanced graphics features that the hardware offers, or that modern software utilizes, so it causes problems like the one you're experience when running proper hardware-enabled 3D software.
Take a look at what you have installed, and we'll have all the information we need. Start by right-clicking on your start menu button, which will pop up a 'context menu', and go to 'Device Manager', just like in this screenshot:
Once you're there look under "Display Adapters" by clicking on it to see what graphics hardware your system includes:
I'd like to know what it says under there. I'd also like to know what driver is installed, so once you see what's listed under Display Adapters go ahead and right-click on whatever display adapter is listed under there and click 'Properties'.
This will pop up a dialog with information about your graphics hardware. There will be a row of tabs across the top: "General", "Driver", "Details", "Events", and "Resources".
Click the "Driver" tab and tell me what it says under "Driver Provider", "Driver Date", and "Driver Version", along with the name of the graphics hardware immediately above that. In this image from my netbook you can see it says "Intel(R) HD Graphics" as the adapter name at the top, next to the screen icon, and then "Intel Corporation" for the provider, "11/10/2016" for the date, and "20.19.15.4549" for the version.
These pieces of information will tell us for sure whether or not your system's graphics hardware's drivers are properly configured, and point us in the right direction. Lets first make sure that your graphics drivers are properly installed and we'll go from there.
Good luck!
