A: If you have a volume licensing agreement, and either have or can find the media, you can use a downgrade license to install and use the number of current licenses you have. You can also ADD users to your license and install the downgrade use of FileMakerPro 5.5/6 clients. You'll need to check with FileMaker Volume licensing for these scenarios.

Otherwise, you will need to find someone selling or donating legal licensed copies. ebay may be a good starting point. Check the Forum here, occasionally people will offer to donate their used copies.
