Getting a MS build fatal error during Visual Studio Install

I tried to install Visual Community and it hung so I uninstalled what components were out there and re-installed. Now I am getting this error: Installed could not continue because required component failed. Any help is appreciated. I did reboot and re-installed and still get the message. Thx. This is my log:

I had the same problem as you, especially with the last message "Error writing to file: Microsoft.Build.Conversion.Core.dll. Verify that you have access to that directory."

The error message is completely wrong and misleading.

The real cause is a missing installation of Microsoft .NET 4.5.2 which you can download from https://www.microsoft.com/en-US/download/details.aspx?id=42642

After I downloaded and installed that (choose the language you need, of course), installation completed.
