This is nothing unusual and can be solved very easily. Just follow our instructions step-by-step and you can successfully install the Framework files.

Step 2 – Usually, the first few links should be to Microsoft’s official sites. So, click the first one in the list.
[WARNING – These search results also contain some unofficial, third-party website links. Do not open those or download anything except the official Microsoft website. These links, sometimes, are malicious and might contain PUPs or any other infections.]
Step 3 – Once you are in the Microsoft download center, scroll down and you shall see the downloading link.

All the crucial .NET Framework updates come through the Windows Update process. So, if you are facing the 0x800F0906 error code, consider installing all the pending updates on your system.
