Are your specs correct? 1GB RAM with a 64-bit OS?

How did you install .NET? Did you run Windows Update to get it? Did you continually run it to get the additional updates? You should have numerous versions of .NET installed.

Do you really need a version that old? I bet if you installed the latest version, the software requiring. Net would work just fine.

As far as I am aware you don't have to "tun on" the .NET framework.

What is the exact error message?

Thank you for your replies.
No, I have 6 mg of ram(my mistake). Yes, I know Windows 7 is outdated, but I like it and it has always served me well........until now!
And yes .NET Framework has to be turned on to load some software(TurboTax and others) and it must be turned on to receive/install MS updates and other software.
I am still exploring how to get .NET Framework to turn on/off.

.Net framework isn't something you normally would turn on and off, it runs in the background and is on all the time.

Go to the link I'm providing below and look at the right side of the page.
Click on the first option, Download .Net Framework Runtime.
Once it's downloaded, run it and let it install .Net version 4.8. It will install it and you should be good to go.

https://dotnet.microsoft.com/download

Your software should run just fine on the most recent version of .Net, usually they are all backwards compatible.
However, if you absolutely need version 3.5, go to this link and scroll all the way to the bottom of the page, it will have 3.5 and all newer versions.

Have you tried installing the latest version from here:
https://dotnet.microsoft.com/download
If not try it then restart your computer. You might just need the new version installed properly,

EDIT:
Sorry - just seen this link was already given in #7.

Always pop back and let us know the outcome - thanks

Work your way through these fixes, until you find one that works.

How to Fix Error 0x80070643 on Windows: 7 Ways
https://www.saintlad.com/fix-error-...

Run the Windows Update troubleshooter
https://support.microsoft.com/en-us...
Here's how:
Download the Windows Update Troubleshooter, and then select Open or Save in the pop-up window.
Notes
If the pop-up doesn’t come up, you might have a pop-up blocker on. If you’re using Microsoft Edge, instructions for disabling the pop-up blocker are here. For Internet Explorer, instructions are here. If you are using a different browser or separate pop-up blocker, check the website of the browser or blocker’s manufacturer.
If you select Save, you need to go to the folder where the troubleshooter is downloaded to after the download is complete, and then double-click the WindowsUpdate.diagcab file to run the troubleshooter.
Select Next and follow the steps in the wizard to find and fix problems with Windows Update .

I have run the Windows Update troubleshooter 2-3 times with no results. One suggested remedy is to uninstall Net Framework. I can not do an uninstall as Net Framework is not listed in my Control Panel programs & features. However, If I attempt to "Turn features on/off'" Net Framework 3.5.1 is listed. It is not on for the subs under it are not on. I turn them on but I get an error message that some of the changes did not take. I have tried other approaches but nothing works. I can not dwnload any updates or files and can not open some program files. I have done it all over and over and rebooted but nothing works.

Typically .Net Framework options are under Optional Updates, Once you scan for updates manually, go to Optional Updates and they should all be listed there. Check off the latest one and install your updates. If it requires any older ones (which I doubt) it will tell you. It maybe that Windows Security is set to shut down any really old ones because of holes in their security. Try the newest one and see if it works for you.

If that still does not work or Windows Update is really not working you can usually fix Windows with Tweaking.com and I have used it for fixing Windows Update when Update Troubleshooter does not work.

You have to be a little bit crazy to keep you from going insane.

If the application was written with .net 3.5 it it will only work with 3.5. The app will look for the version it is build with.
The programmer can rebuild the app with a higher .net version (possibly with some modifications) and distribute it as an updated version.

@#16 That's no longer true. If you have .NET framework 4.5, or later installed, then apps compiled for earlier versions will work just fine.

https://docs.microsoft.com/en-us/do...

"The .NET Framework 4.5 and later versions are backward-compatible with apps that were built with earlier versions of the .NET Framework. In other words, apps and components built with previous versions will work without modification on the .NET Framework 4.5 and later versions."

@ ijack. You have to read the whole story.
https://docs.microsoft.com/en-us/do...

Apps compiled from V4.5 onward are likely to run on all 4.x versions.
Apps compiled on V3.5 will need o have the config-file modified. And still issues may arise running on V4.5!

You'll note that that document refers to .NET 4.0. The document I linked to applies to .NET 4.5 and later.

Thanks for your responses.........I am closing this thread out. I tried everything suggested for Windows 7 and my issue (tried them all about 3 different times) and nothing solved the problem. Thank you.......I am now seeking help from another source.
