sumatrapdf v3.1.2 [Approved]
sumatrapdf package files upgrade completed. Performing other installation steps.
 The upgrade of sumatrapdf was successful.
  Software install location not explicitly set, could be in package or
  default install location if installer.

Chocolatey upgraded 1/2 packages. 1 packages failed.
 See the log for details (C:\ProgramData\chocolatey\logs\chocolatey.log).

Failures
 - sumatrapdf.commandline (exited -1) - Error while running 'C:\ProgramData\chocolatey\lib\sumatrapdf.commandline\tools\chocolateyInstall.ps1'.
 See log for details.

What is Expected?

The download should be successful, not fail and write an error.

How Did You Get This To Happen? (Steps to Reproduce)

Within our network environment, cup sumatrapdf -y.

In our environment, (new-object System.Net.WebClient).Proxy -eq $null
is true, as is [System.Net.WebRequest]::DefaultWebProxy -eq $null. This
means the IsBypassed() method is being called on a null object in several of choco's supporting scripts.

(GH-1141) Fix: Constant Proxy Null Reference Error
eb39536 
In some environments, (new-object System.Net.WebClient).Proxy -eq $null
is true, as is [System.Net.WebRequest]::DefaultWebProxy -eq $null. This
means the IsBypassed() method was being called on a null object. This
checks the object's existence before using that method.
