Issues with .NET Framework 4.7. How to put it right?

Question

.NET

After Autocad 2015 asked me to install .Net framework 4.6.2 when installing on my Windows 7, I decided to agree with him and put it instead of my 4.7. Immediately after I installed it, Visual Studio 2019 stopped working (I needed 4.7 and higher), and I needed both programs. When the autocad was no longer used, I decided to demolish it and return my framework back, but after removing version 4.6.2 and installing 4.7, complete hell began: half of the necessary applications stopped working (including discord, and the already mentioned Visual Studio). Reinstallation, recovery, cleaning up the remnants of versions using the Cleanup Tool also did not work. Is there any solution for this problem? I rummaged through the Internet in search, the deadline for the project is next week, the only option I see is reinstalling my Windows,

Answer 1

.net framework 4.7 lives quite normally in parallel with 4.6. Set first 4.8, and if the autocad will work out - install 4.6.
