Approximately 3MB. Only for use on PCs because Microsoft Works is NOT available for Mac.
The Service Manager CD includes database and spreadsheet files that are not a stand-alone program. You must have Microsoft Works (version 4.5 or higher) to use this product. Microsoft Works is occasionally preinstalled on PCs, so check your PC closely to see if you have this program. If not, it is available from a variety of sources for as little as $20 (up to $100 for the most deluxe version, but the basic version is all you need). Microsoft Works is NOT available for Mac computers.
