I have a Windows 10 PC, and when I try to install .NET Framework 4, I keep getting this error with a lengthy description along with the code, 0x800c0005. I am not able to fix this error and I need the Framework installed on my system as soon as possible. So if someone can suggest me ways on how to do this, it will be really helpful.
This error code usually occurs when there is a download failure especially in the case of certain DLL files that are not registered correctly or if the firewall in your system does not allow it to connect to the internet especially for https connections.
Try to do any one of the following.
Run the fix mentioned under the section “0x80072ee7” from this link,
Re-register the following DLL files by opening the command prompt and typing in the following commands. Press enter after each line.
“regsvr32 Softpub.dll
regsvr32 Wintrust.dll
regsvr32 Initpki.dll”
Click on ok and restart your computer. Now check if you can install the framework.
If you need to install Microsoft .NET Framework 4 and you have Microsoft Windows 10, it won’t be possible because in the first place, your operating system is not supported and that’s the most vital part in the installation of any software. Microsoft .NET Framework 4 supports Windows XP Service Pack 3, Windows Vista Service Pack 1, and Windows 7.
For servers, it supports Windows Server 2003 Service Pack 2, Windows Server 2008, Windows Server 2008 R2, and Windows Server 2008 R2 Service Pack 1. If you badly needed to install Microsoft .NET Framework 4 on Windows 10, your best option is to install Microsoft .NET Framework 4.7.2. This is a highly compatible, in-place update to .NET Framework versions 4, 4.5, 4.5.1, 4.5.2, 4.6, 4.6.1, 4.6.2, 4.7, and 4.7.1.
Go to Microsoft .NET Framework 4.7.2 offline installer for Windows and download the offline installer. There is a separate download for Windows RT 8.1. So, for users with Windows RT 8.1, click the download link specific to Windows RT 8.1.
