Silent install vcredistx86.exe (2005, 2008, 2010)

Dear maestros's
I can't figure out how to silently install these redistributables with vbscript. I surfed the internet and tried different solutions given by other people, but no real solution yet. I'm using vbsEdit.
Several stements used f.e.;
strCmd = "\\zzzzz\c$\zzzzzz\vcredist.exe /q"
objShell.Run(strCmd),0,True
 
strCmd = "\\zzzzz\c$\zzzzz\vcredistx86.exe /q:a /c:" & """msiexec /i vcredist.msi /qn"""
objShell.Run strCmd,0,True
 
Can somebody give me a clue how to do it ???
