why cant vcredist_x86.exe installed quietly?

Question

I need to install vcredist_x86.exe (Microsoft Visual C++ 2010 Redistributable Package) quietly. I entered "vcredist_x86.exe /q" on cmd.exe. However, vcredist_x86 didn't install successfully. I used Task Manager to inspect what happened. I found out that a process named "msiexec.exe" keeps alive until you kill it.

VC++ 2005 is made with older version so arguments /q (/qb) or /passive /norestart will not work (mentioned here: http://blogs.msdn.com/b/astebner/archive/2010/10/20/10078468.aspx).

For quiet mode use /Q switch, to get all parameters run vcredist_86.exe /?
