C# How to Detect excel 2003 professional edition is installed?

How can we check whether excel 2003 professional edition is installed on users machine?

I can detect Whether excel 2003 is installed or not using registry key.

If below registry key is exist then excel 2003 is installed in user machine.

HKLM\Software\Microsoft\Office\11.0\Excel

But Now, I want to detect whether installed excel 2003 is professional edition or not. So is there any way to do same.

Any help would be highly appreciated.

Check this in registry key:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\App Paths

or

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\App Paths

Version numbers are:

7.0 -97

8.0 - 98

9.0 -2000

10.0 -2002

11.0 -2003

12.0 -2007

14.0 -2010

You can also check here:

HKLM\Software\Microsoft\VERSION\Common\InstallRoot

Where VERSION is the version of Office you are looking for.

EDIT: Answering to your comment.

You can get the product version (Standard or Professional) by querying the installed software with WMI:

 ManagementObjectSearcher mos = new ManagementObjectSearcher("SELECT * FROM Win32_Product");
                foreach (ManagementObject mo in mos.Get())
                {
                if (mo["Name"] != null)
                {
                    string ProductName = mo["Name"].ToString();
                }

            }

This will get you the product version of all installed software, just search office entry and you should get the package name that appears in control panel.
