title: Cvxpy requires MS Visual C++ 14.0 although it is installed
body: <p>I have been trying to install cvxpy an several windows machines (Win 7 and 10) with Anaconda without success. I foolowed the instructions (<a href="https://www.cvxpy.org/install/index.html" rel="nofollow noreferrer">https://www.cvxpy.org/install/index.html</a>) and also installed the recommended build tools. However, pip doesn't seem to find them.
  Strange thing is: Half a year ago, I did the same thing with own PC and it was absolutely painless. I noticed that on the machines a have problems with, Anaconda is installed for All Users, while on my machine it's only for me as user.
  So I installed the VCForPython27.msi with the ALLUSERS=1 option, but still, cvxpy doesn't want to be installed. I couldn't find anything on the web. Everybody recommends to install the build tools, but they are installed!</p>
  
  <p>Thank you for any help!</p>
  
  <p>The error report is very big, so include only a few things:</p>
