him a link on my app server for installing Excel

file exist before loading

You can use CreateObject("Excel.Application") and see if an error is
generated. Or you can look in the registry to find the installation path for
Excel if it's there. I'd post this in an Excel group where they probably
would have more information on what registry keys to look at.

You can look at the error status or you can use one of the many different
methods to check if a file exists in the file system. WSH has the
FileSystemObject.FileExists method, there are Win32 API calls that also will
tell you that (FindFile and relatives).
