check if office is installed in 64 bit Win OS using registry

Question

I trying to check if office is installed using registry. I am able to verify for 32 bit OS using the following regkey

"..HKLM\SOFTWARE\Microsoft\Office\14.0\Common\InstallRoot" + "Path"

But how do i check when using a 64 bit OS? This key does not exist on a 64 bit OS for either 32 or 64 bit Office. (Checked on both Win7 & Win 8)

Answer 1

I finally tracked down the answer I was looking for. This forum thread has an answer that suggests some registry keys to try.
