Software requirements are low. It should suffy you have Windows 95 or higher. Higher versions of Windows should be compatible.
The program has been tested on Outlook for Win95 and Outlook 2002. We expect it to work too with previous and latter versions.
Hardware requirements are nihil; the slowest Pentium will be more than enough and the needed hard disk free space is about 1MB only... . For big pst files though we recommend a fast hard disk and a fast processor (1GHz or higher)
