As you see in here i downloaded all the parts of Siemens Tia Portal V14.
Why i chose the Basic software of Tia Portal ? I am going to work just on S7-1200 and that’s why i installed Tia Portal Basic on my computer. And after the trial if you wanna buy licence, Tia Portal Basic is more cheaper than Premium one.

Click Simatic_Step_7_Basic_V14, and then follow the steps “next,next”.

Initializing…

Note: I suggest to beginners, go ahead with Typical Product Feature.

Accept the licence terms and Go Ahead.

And finally after the click button on security term, welcome to Install.

After successful installation, restart your computer and let the modules integrated to your software.
