I am trying to install Net framework 4.8 on a new Windows 7 machine, but when I run the installation file (both online or offline ones), it fails with the following error:


D:\a02a9e9bba0a93cf7b\SetupUtility.exe - Signature verification for file SetupUtility.exe (D:\a02a9e9bba0a93cf7b\SetupUtility.exe) failed with error 0x800b0001 (Unknown trust provider.)


No FileHash provided. Cannot perform FileHash verification for SetupUtility.exe
File SetupUtility.exe (D:\a02a9e9bba0a93cf7b\SetupUtility.exe), failed authentication. (Error = -2146762751). It is recommended that you delete this file and retry setup again.

Final Result: Installation failed with error code: (0x800B0001), "Unknown trust provider. " (Elapsed time: 0 00:00:33).





I tried repairing windows update using Windows repair software, and the error I get when running Net frmework installer changed:


Also, when I try to install Netframe work quality roll-up from windows update, it fails with a similar error but different code (0x800b0003)





I tried running Windows update troubleshooter, Windows update readiness tool (As stated here), installing with the diagnostic startup or even safe boot. Also, I tried installing certificates for setupUtility though file properties. None helped.


I faced all of these problems when I tried to solve the issue with installing Visual Studio 2019, which when I try to run the installer, it gives me a certificate or signature error.
