Visual Studio 2015 Community: Setup Failed! Installation Error

I am trying to install Visual Studio 2015 Community (with updates) on Windows 7 x64, but in the start of the installation, when it is about to install Build Tools 14.0 (x86) it fails. I do not know why this happens and i have tried to find answers but nothing i do seems to work. Please report if you possibly know and answer and a solution.

Here is a screenshot:

It's in swedish but it says:

Microsoft Build Tools 14.0 (x86): A fatal error occured during installation

Microsoft Visual Studio Enterprise 2015: %1 is not a valid Win32-program

Visual Studio Update Prerequisite: %1 is not a valid Win32-program

Microsoft .NET Framework 4.5.1 Multi Targeting Pack: User stopped the installation

Please help...

Here is the a part of the log file i think the error is in:

Below are the steps I took:

1. I restarted the system.

2. I went to task manager and end task for all Microsoft Visual studio setup running. In my case, I had 3 running at the same time. This can be seen around here: task manager. end all the task relating to Microsoft visual studio setup

3. Goto programs and features, visual studio community --> change --> repair or if you have the .ISO file, you can run it again. choose repair for either option. I used the .ISO file NOTE: I was internet connected when running the repair.

4. Boom!!! it starts repairing and then you are good to go.

5. After repair, it will request for a restart. Click on restart and then you have your visual studio up and running
