I'll copy and paste some of the info from the other site then, if that's okay. My operating system is Windows 8.1 and I'm trying to install the classic version.

Not sure if I should post this here, but I've posted issues here before and the support was excellent, so i thought I would try again. I posted this on the microsoft community forums as well but answers are scarce there and usually unhelpful.
So, I recently purchased a used laptop. (It should be noted that when I got this laptop the resellers had upgraded it to windows 10, which the computer couldn't properly handle, so I wiped the hard drive and installed a fresh version of Windows 8.1.) I noticed that many of my programs were having issues installing, most of them saying they require the latest version of Microsoft.NET Framework. So, I downloaded Microsoft Framework 4.7.2, and tried to install it. At first, the installation failed and had an error message. I don't remember what it said, unfortunately. Then it started saying it was already installed. I checked my windows features to see if this was true, and it didn't appear in the features, or in the place where you uninstall programs. However, I did have an older version of Microsoft Framework, I think 3.0, but I'm not sure. I thought maybe the failed installations had left residual files behind causing my computer to think it was already installed. So after that I tried deleting the Microsoft.Net folder like an idiot, which just made things worse. At that point I started googling fixes, and found a tool that completely removes all versions of Microsoft.Net Framework from your system. I ran it and removed everything, but the installer still says the framework is already installed, and I am still getting errors from programs saying they need the framework to run. This is the tool I used to cleanup: https://www.raymond.cc/blog/wp-content/plugins/download-monitor/download.php?id=2599
Edit: I ran a setup verifier tool for microsoft net (this one:https://www.raymond.cc/blog/wp-content/plugins/download-monitor/download.php?id=3006) and collected logs, and I also ran the official net repair tool and collected logs. The logs are attached. (I'll send the logs on here as well if you need them.)
So basically I worked through with the helper on the other website and I believe I fixed the microsoft framework by running an sfc scan thing, and then running another command to repair the corruption. After that the paint installer wasnt crashing immediately, but still wasn't working. (Read Above)
Sorry if this is hard to understand, there's a lot of information I had to write and I'm horrible at explaining things.
