title: Can't apply KB3165756 to Visual Studio 2015 Professional
body: <p>I have a licensed version of Microsoft's Visual Studio 2015 Professional operating on Windows 10 Enterprise. The Help/About displays this, in part:</p>
  
  <pre><code>Microsoft Visual Studio Professional 2015
  Version 14.0.25424.00 Update 3
  Microsoft .NET Framework
  Version 4.6.01038
  
  Installed Version: Professional
  </code></pre>
  
  <p>Visual Studio has been pestering me to apply KB3165756 for more than a week, so as to update things from 14.0.25424.0 to 14.0.25425.01. I select the link and it downloads vs14-kb3165756.exe to my computer. I start this program and run it. After a short delay (and getting through a few security prompts), the program aborts with this display:</p>
  
  <p><a href="https://i.stack.imgur.com/byU8w.png" rel="noreferrer"><img src="https://i.stack.imgur.com/byU8w.png" alt="enter image description here"></a></p>
  
  <p>I click on the link to examine the log file (the common issues and workarounds link is completely worthless so far as I'm able to see) and I get quite a long laundry list of errors near the bottom. This is the <a href="http://www.infinitefactors.org/misc/dd_patch_KB3165756_20160811152242.log" rel="noreferrer">error log file</a> I get.</p>
  
  <p>I have re-tried this any number of times, including completely shutting down the computer and rebooting and then re-trying the operation. It always fails at the same point. It also always adds the point about "user cancelled installation." But I didn't actually participate. All I did was watch the installation process acquire some files and then fail. Perhaps just a few minutes' time to get there.</p>
  
  <p>(I do have a few add-ons in Visual Studio 2015. I can provide a complete list, if that is needed. Or I can check an item if someone feels it's important to check for particular ones. Most of them are from Microsoft, though. And no, I have not removed them all and tried to go back to the beginning installation process and then re-apply everything in some different order.)</p>
  
  <p>I'd appreciate any productive thoughts about how to get this patch applied. I'm getting to the point of considering a complete uninstall of Visual Studio, a re-install from the original DVD, and then re-application of patches. (But, of course, I'd like to avoid that.)</p>
