Windows 8 Can't find executable in path with "where" command

I added the following line in my System Variable Path

"C:\Program Files (x86)\FontForgeBuilds\bin"

I can then run fontforge:

C:\Windows\system32>fontforge -v

But I need to be able to run where fontforge from a script. This produces:

C:\Windows\system32>where fontforge
INFO: Could not find files for the given pattern(s).

Why can't where find the executable path when I have it added to the environment variables?

Answer

I don't know why it didn't work, but I re-installed fontforge to a different directory (with no spaces) and it seems to work now.
