Urgent - Check the installation of EXCEL or EXCEL Viewer on Client
Fi
To my knowledge, no. I think you must do a regread and check on the result
(works for both the viewer and the full version of Excel), or do a
CreateObject("Excel.Application") (works only for the full version of Excel).
Note: If the Office version is 2000 or XP, you can also use the MSI object
(WindowsInstaller.Installer) to get/check installed features (eg. Excel).
