Unable to install .NET Framework on Windows 7 - fails with error code (0x80070643), "Fatal error during installation
Dell Optiplex 7020, Windows 7 Pro SP1, 64 Bit
I am unable to install the .NET framework.
Windows had become damaged, so I restored it from a previous image backup.
Everything worked fine after the backup except for the .NET framework.
I have downloaded the 4.7.1 stand-alone, but the installer stops with errors. Same happened with 4.6.2
I used IOBit Uninstaller (free) and removed all the .NET components that could be found there.
I tried to turn off .NET 3 using the Windows features uninstall, but that gave me errors as well.
I ran CCleaner Free, did all the registry repairs. I ran twice because the .NET issues weren't cleaned up after the first run.
I have included the simple Installation log below
Thanks

Here's a development. After running the Net Framework Repair tools, and doing the uninstall/repair of NET framework, I noticed that QuickBooks 2007 stopped working. While reinstalling QuickBooks 2007, I noticed that NET Framework 1.1 needed to be installed. This install was successful.
So - I can install version 1.1 I can try the repairs again.

Thanks for the update. .NET Framework 1 should be OK on Windows 7 - nothing later.

Nothing seemed to help. I will have to reinstall Windows 7 Pro, or maybe upgrade to Windows 10
Windows 10 works better than Windows 7 so that is the way to proceed if you are willing

If I upgraded to Windows 10, would the Windows 7 components that are preventing the proper installation of Dot-Net likely be removed and replaced?
I figure that I'm looking at a Windows reinstall as the only repair solution now, and there would be less work installing and configuring applications if I upgraded to 10 (and the upgrade didn't pull along what ever damaged software/settings are messing things up now)

If you update to Windows 10, it will update all the .NET components
>> and there would be less work installing and configuring applications if I upgraded to 10 << that may be so - but you never know what else happens. you decide if you go on with W7 or W10

.NET Framework Setup Verifier doesn't help, links me to NetFxRepairTool.exe, which is unable to repair.
