I have downloaded the file xampp-win32-1.8.3-5-VC11-installer.exe and basically it has managed to crash my computer. If I launch the file directly from Chrome (my browser) nothing happens and one of the chrome.exe process start using the processor core 100%. If I navigate to the file and executes it from explorer, nothing happens and I get an explorer.exe process using the processor core 100%. If I right-click the file and choose "Run as Administrator", nothing happens but at least I get no process using the processor core 100%.
My system is running Windows 7 Home Premium x64 and everything else is running just fine.
It seems to me that the installer might be broken, or installation is more complicated than normal.
