title: Conda stuck on Executing Transaction
body: <p>I have Windows 7 Enterprise machine on the network at work. I installed the Conda version 4.5.4. Installing pandas, openpyxl, went smoothly. But soon after trying to install Dash, Conda was stuck on 'Executing Transaction'. I tried a different package and same thing. I then proceeded to install Conda 4.5.5 and that successfully installed. So when I went back to installing Dash, it went back to being stuck on 'Executing Transaction'.</p>
  
  <p>Any suggestions as to what the root cause would be?</p>
  
  <p><strong>Update:</strong>
  Nor reply needed. I just deleted my existing environment, then created a new environment. I installed Dash as the first package and this time it installed, but it took 15 minutes if not longer.</p>
