We have an EXCEL 97 spreadsheet containing userforms and controls etc... which we have to deploy to clients which may be running various O/S's i.e Win98, 2000, NT4. Our only requirement will be that their system runs EXCEL97 or above. My questions is are there any utilities available which can package or install our spreadsheet app so that it runs on various target machines without those annoying eror message about missing objects, DLL's etc. Alternatively is there a way to manually figure out what DLL are required to be installed for a particular target machine.
