I need to install visual studio 2013 but it shows this dialog:

I guess that this problem can be solved by installing some required files that makes Windows 7 functions as Windows 8.

Answer: 
According to the [System Requirements](http://www.visualstudio.com/en-us/products/visual-studio-ultimate-with-msdn-vs#Fragment_SystemRequirements), you need to install [Windows 7 Service Pack 1](http://windows.microsoft.com/en-us/windows7/install-windows-7-service-pack-1), which (judging by your screen shot) you are currently not running.
I had a similar problem and I found a solution. A heavy one. You delete the version installed with Revo Uninstaller with Advanced mode - in order to remove registries and connected software. After that I used TuneUp 2014 registry editor and searched for "Visual Studio". It found 900 more entries in the registry. I deleted all of them and installed clean again. It solved my problem.
