problem installing solidworks 2014

hi,

I'm having some problem while trying to install solidworks 2014 on my pc, I'm running windows 8 64.

I keep on getting this error :

"Internal error: The Windows Installer for this product component did not run as expected: set_QuiteModeActions."

all the rest was installed just fine (eDrawing, explore, composer......)

I've read in some places I need to change the regkey wow64 but it dosn't appear in my registry editor.

thanks for the help!!
