Edited Unassigned: Unable to Upgrade VS 2013 Extension from 1.6.0 to 1.6.3 [145]

When I try to 'Update' the extension through visual studio (2013) I get an error "The extension could not be installed because the following error occurred: An exception occurred during a WebClient request.".

This is occurring on our work computers and I think it may be a firewall issue at our office. However to resolve the issue, I need the web address that it is trying to get to.
This is just a guess that this is the issue. The activity log doesn't really give that much useful information. (Except from activity log is below)


I have also tried to manually install from Visual Studio Gallery http://visualstudiogallery.msdn.microsoft.com/1f6ec6ff-e89b-4c47-8e79-d2d68df894ec?SRC=VSIDE but when you download from there, you get an installation error: "The file is not a valid VSIX package." (Install Log is below).

Are you able to help?
thanks
Sylvia
