When fiancé wants to play The Sims 3 on fresh Windows 7
Problem:
After installation of The Sims 3 and first run, wild message appeared:
The program can’t start because MSVCP100.dll is missing from your computer.
Try reinstalling the program to fix this problem.
Computer: Samsung NP300V5A-S03PL with fresh Windows 7.

Solution:
Install Microsoft Visual C++ 2010 SP1 Redistributable Package in x86 version, but I recommend to install x64 versions too.

Story:
One day fiancé realised that I have The Sims 3 on my Origin account and she wanted to play it badly. So I wrote her instruction how to install it on her computer. Unfortunatelly I created this instruction on Windows 10 where everything worked fine.
When she started installing it then she had two problems: one with starting Origin installator and next with starting The Sims 3.
First one was showing error as below:
The application was unable to start correctly (0xc000007b).
The cause was missing Microsoft Visual C++ Redistibutable Packages for Visual Studio 2013 (https://www.microsoft.com/en-ie/download/details.aspx?id=40784).
After installation of Origin, downloading and installtion of The Sims 3 there was second problem described above.
Every solution on internet said to install Microsoft Visual C++ 2010 SP1 Redistributable Package, but didn't mention about x86 version. After installation of x64 version of 2010, 2008, 2012, 2013, 2014, 2015, ... I tried blind shot with x86 version of 2010. Like you see - it helped!
P.S. Special thanks to Izabela for her patience :)
