Question: Is there a way to detect the SIM phone number on a mobile device while using Meteor?
Moreover, what is the correct behavior to have and precautions to make to log users using their phone number (like in Whatsapp or Viber for example)?

Thank you in advance.

Answer: 
You have two options:

1. Install Microsoft Windows SDK
2. Copy these files to the machine you are trying to build.

take a look at these answers:

[Task could not find "AxImp.exe"](https://stackoverflow.com/questions/5923258/task-could-not-find-aximp-exe)

["Task failed because AXImp.exe was not found" when using MSBuild 12 to build a MVC 4.0 project](https://stackoverflow.com/questions/21373792/task-failed-because-aximp-exe-was-not-found-when-using-msbuild-12-to-build-a-m)

[Task failed because "AxImp.exe" was not found, or the correct Microsoft Windows SDK is not installed](https://social.msdn.microsoft.com/Forums/vstudio/en-US/e56fd9b3-dbea-4545-a5a5-f1af0e333ad7/task-failed-because-aximpexe-was-not-found-or-the-correct-microsoft-windows-sdk-is-not-installed?forum=tfsbuild)
I had the same issue when I try to build the VS2015 solution file with Jenkins on Windows 2012 server after commit to SVN. Tried to copy AxImp.exe and related binaries and settings but failed. SO I had to install the windows 8.1 SDK and that made the successful build via Jenkins CI server.
Hope this helps someone.
