title: ReInstall Visual Studio 2015
body: <p>My Win 10 version of Visual Studio 2015 Community edition failed to load with error "cannot find one or more components .Please reinstall the application".</p>
  
  <p>I've tried repairing it but received nondescript errors so cancelled the repair (which also reported similar errors and eventually that 116 out 120 components had been repaired - iirc).</p>
  
  <p>I then tried an uninstall, but that crashed windows. </p>
  
  <p>On reboot, the VS 2015 uninstall options screen was displayed. Tried uninstall again but progress bar wasn't moving. Successfully cancelled it.</p>
  
  <p>How do I get a working copy of VS 2015 running again (without breaking anything else on my machine)? Can I reinstall a new copy over the top of the old one?</p>
  
  <p>Thanks in advance.</p>
