Corona Installer cannot install some of the files


This solution applies if the Corona Renderer 1.5 or newer installer finished with some errors, and it could not install some of the required files.


If the file which cannot be installed is one of the following:

  • vc_redist.2015.update3.x64.exe
  • Windows6.0-KB2999226-x64.msu
  • Windows6.1-KB2999226-x64.msu
  • Windows8.1-KB2999226-x64.msu
  • Windows8-RT-KB2999226-x64.msu

Then it usually means that there was some problem with Windows Update.



To solve the problem:

  1. In the installer, on the "Install Type" page select "Unpack files"
  2. Select a desired location where the files should be unpacked
  3. Press the "Unpack" button
  4. Go to the location where the files were unpacked
  5. Find "Microsoft Dependencies" folder and open it
  6. Try installing all the files which are inside manually. If it is impossible, try installing them as administrator (right click > run as administrator).



If the files cannot be installed manually:


Start command line and paste the following code:


net stop wuauserv


After seeing the message "The Windows Update service was stopped successfully", try manually installing the Microsoft Dependencies again. If it is still impossible, please try restarting your computer, and then installing the dependencies once again.
