detect the installed programs of MS Office

[almorr]

first i'll explain the situation.
We have some licenses of MS Office 97/2003(complete), then we bouth some license just for Excel and Outlook2007 .
But we still to install and use the 97 or 2003 versions. Some PC has just OL, others has Access or Excel
I need to know where and which software is installed.
The problem: if i install, for example, just the OL from the CD MS Office 2003, on the liste Add/Delete the programs it's displayed as MS Office 2003, so on Lansweeper's software report i see MS Office 2003, not OL 2003

I know, i can use a file scan to detect the msaccess.exe or others, but it was not always installed by default path.
And often, we have a mixed installation: Access 97 and OL 2003
So my question: is it possible to detect what exactly is installed on PC(MS Office soft and the version) from the Windows registry or by an other way?

That will be difficult.

I'm not really sure but I believe that when you buy a license for excel/outlook,... and other applications that they have a seperate installer which shows the correct name in add/remove programs.

When you install from the full office cd it will display "office 2003"

Your best bet will be the registry:

Key : HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office
Under this key are subkeys for each version of office
