I found it under 
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\{2A076531-42D9-4231-8A60-323EBE603E2E}.

but first, I'm not sure the Guid part is fixed, and second the 
installation path is not in this key :(

But I found HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows 
Installer XML\3.9

unfortunately, the version number is in it, so I will have to include 
more logic :(
