Thanks for your reply. I am using Landesk 126.96.36.1993. However in that when I am running a query under Computer> software> I could not find any 'product' to choose. There is only 'Product version' however that only gives few numbers to choose from the right pane.
Let me know if you are using a different version of Landesk.
If it was installed as part of office, it might be a little more tricky to find. You might have to query for msaccess.exe and get the version info from there.
