title: Errors in installing Visual Studio 2015, regarding "Microsoft Visual C++ 2015 Redistributable"
body: <p>I am stuck since 2 days with this simple installation process of Visual Studio 2015 from my university portal (vs_communityENUS.exe which is a 3260 KB application). I am not new to installation and troubleshooting but this one has got me insane.</p>
  
  <p>Every time I install it it throws me errors:</p>
  
  <ol>
  <li><p>Microsoft Visual C++ 2015 Redistributable (x64) - 14.0.23918 : Another version of this product is already installed. Installation of this version cannot continue. To configure or remove the existing version of this product, use Add/Remove Programs in the Control Panel.</p></li>
  <li><p>Visual Studio 2015 Update 3
  Microsoft Visual C++ 2015 Redistributable (x64) - 14.0.24210 : The installer failed. Another version of this product is already installed. Installation of this version cannot continue. To configure or remove the existing version of this product, use Add/Remove Programs in the Control Panel. Error code: 0x80070666</p></li>

  <p>I checked my control panel but I did not find any files with the above name. Than, I got this <a href="https://www.youtube.com/watch?v=Qi0deGqmo2g" rel="noreferrer">amazing link</a> that helped me remove any previous version of visual studio I have in my machine but a fresh installation after that also threw same errors. </p>
  
  <p>I am badly stuck, what I want is a simple visual studio version compatible to windows 8.1 and can successfully integrate with opencv, qt and vtk.</p>
  
  <p>Any help in this regard is highly and respectfully appreciated.</p>
