Packaging problem in unreal 4.11 - Receiving 'error: unknown error' msg

Packaging was no problem until I installed Visual Studio 2015. I thought the problem might be the game itself, but any project I try to package gets the same error.

I am including a txt with the log of just a base project I made to test the program, nothing was done to it except what was necessary to create a TPS project. I got the same results when I tried to package.

I place color indicators in the text for clarity. (Example: IN RED)

I DL’d the engine from here at UnrealEngine and Visual Studio from Microsoft.

I hope you can help. I really want to use this and was enjoying it, but not being able to move it completely vexes me.

it is telling you what the problem is about in that txt file.

Visual C++ 2015 toolchain does not appear to be correctly installed. Please verify that “Common Tools for Visual C++ 2015” was selected when installing Visual Studio 2015.

Thank you SO much! I only did a custom install and add just VS. I had no idea. I did a modify and installed the additional tools, and everything works fine now. Again thanks!
