Cannot Install .NET framework 4.8 on Windows 7

Microsoft_.NET_Framework_4.8_Developer_Pack_20211206104955.logMost installers from Microsoft fail to install with the certificate error.
When I look at the certificate, it is not valid in Windows 7, but the certificate is valid in Windows 10.

I'll go out on a limb here: Check on your system to see if you have Microsoft updates KB4474419 and KB4490628 installed. If any of those two are missing download it/them from Microsoft, install them, reboot, then try installing .NET 4.8 again. If you do need to install them remember to chose the correct download for your system i.e. (going by your signature) Windows 7 x64.

Grrr... dealing with "windoze" is why I have grey hair.
Accidentally took off a bunch of NET stuff today because there is no easy way to see what software uses it and
luck would have it that the first program I tried to fire up requires the NET framework.

MS sends you on a wild goose chase and they don't bother to tell you the latest version will not install or what the right one is (v4.8), or that the right one will not even install..... END OF RANT.

Now I have done everything mentioned here and the POS still will not install.
Almost an entire day stolen by the clowns at MS. IMHO they do this on purpose to try and coerce you into their latest OS and seriously some of them should be in jail for the stuff they pull.

Can anyone save my sanity and point me in the right direction?
Thanks in advance

2 Updates Worked ! for this new installed Windows 7 where nothing is installed, this solution should be #1 Search Results on Google.

OBS is now installed without any problems thanks ? too .NET 4.8

This is my third day of trying to get the NET framework back on Windows 7 Pro.
I have mainly been led in circles from my Google searches.
I just tried the windows troubleshooter which tells me that Net v4.0 needs to be installed
and when I try to install V4 it fails.

With windows machines it seems like the financially prudent way to solve problems is to go out and hand your money over to MS for
their latest and greatest new OS or even throw the PC into a fire.

It is fast approaching the point where it is going to be cheaper to buy a new computer -- just like MS has it planned IMHO.

With MS they have even made it difficult to reinstall the OS since they don't giver you disks any longer.
