KB4481480 install error
2019-01 Security and Quality Rollup for .NET Framework 3.5.1, 4.5.2, 4.6, 4.6.1, 4.6.2, 4.7, 4.7.1, 4.7.2 for Windows 7 and Server 2008 R2 for x64 (KB4481480) install error

It's been nearly 2 months that I am having trouble installing this update. All I get is "install error". I tried manual update and install with no results whatsoever. How can I solve this issue. Thank you --103.231.162.134 (talk) 01:33, 3 February 2019 (UTC)
 * You are not alone with this problem. You can only wait until Microsoft fixes this update. Ruslik_ Zero 08:20, 6 February 2019 (UTC)
 * Here is something that sometimes works (for me, maybe one time out of five);
 * Grab another hard disk. Most people have an old, small one floating around. If you don't. here is one for $39: . Remove all formatting with DBAN.
 * Do a clean install of your OS. Then go through the tedious process of installing every available update (required and optional).


 * Did it work? Now you know that a clean install and reinstalling all apps will fix it. Now you need to decide whether to do that on the hard disk you use all of the time. :(


 * Still fails? Try this (still on the new HDD where it doesn't matter if you screw it up):


 * Microsoft has stand-alone installers for most (all?) Windows updates. Try that.


 * says "All updates for .NET Framework 4.6, 4.6.1, 4.6.2, 4.7, 4.7.1, and 4.7.2 require that the d3dcompiler_47.dll update is installed. We recommend that you install the included d3dcompiler_47.dll update before you apply this update. For more information about the d3dcompiler_47.dll, see KB 4019990. Try that.


 * Try the solutions various people suggest here:

 * Hi everyone. None worked. I don't want to re-install OS. Thanks--103.231.162.134 (talk) 20:05, 10 February 2019 (UTC)


 * Are you saying that you tried the fresh hard drive / clean OS install as I suggested and it didn't work? --Guy Macon (talk) 01:55, 11 February 2019 (UTC)
