This program is part of Office 95 and Exchange (Client) 4 and 5. But I get the impression you can download it free. However, it might need a valid license number to be installed.
You might need to find an Office 95 or Exchange (client) CD ROM (with license number) on eBay.
Hope this helps.
Anybody know where I can donwload this program? Thank you
