Error code: 0x00000490 while installing .Net Framework

Question

I'm having problems installing the .net framework 4.6.1 due to the "Element not found" error. I tried searching the error code to no avail, and couldn't find anything related to the error on the support site for microsoft, so I was hoping that asking here might lead to more success. I have the log right here if you'd need it.

Final Result: Installation failed with error code: (0x00000490), "Element not found. " (Elapsed time: 0 00:01:53).

I hope this helps, I'd like to know how to fix this as soon as I can. Also, I'm not quite sure what topic this fits under, and I apologize if it's in the wrong one.

Hi,

My computer is run under Windows8.1 Enterprise K version.

When I installed 3rd party software, I saw a message the SW needs .NET framework. And all the installation procedures were completed successfully.

However, when I tried to run this SW, I got the message that the SW needs .NET framework installation. I am confused. On my computer, .NET framework is already installed. 

I chose Yes to install, then I met the error message Error code: 0x00000490.

Then I have tried to find how to resolve, finally I tried to follow your recommendation

"Troubleshooting Blocked .NET Framework Installations and Uninstallations"

I ran regedit as above column recommended, and tried to find .NET framework in the registry. There is no registry subkeys related .NET framework in the both Windows registry folders under

HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Compatibility Assistant\Persisted**** and  

HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers

So that I cannot use SW which needs .NET framework.

I have 2 PCs with same Microsoft Windows 8.1 Enterprise K version.

.NET framework works well on one PC, and doesn't work on the other PC.

I cannot understand what happens and what to do.

Your kind help will be highly appreciated.

I just wound up updating to windows 10 and it fixed the problem. I had tried the above suggestions and out of frustration when they didn't work, gave in to the "Update to windows 10" prompts my computer had been bombarding me with. I'm sorry I can't provide any more help than just update but that's what I did and I haven't had to worry about not having files when installing things since. Good luck, and I hope you fix your files without having to update.
