The Digital Frog 2.5 had  a problem with the Fast Find feature that could not be fixed with an internet update, so we took the opportunity to upgrade to Mac OSX Intel and to Vista before releasing The Digital Frog 2.5a.


Installation instructions for The Digital Frog 2.5(a) single user version can be found in the booklet that accompanies your copy of the CD-ROM. If you purchased a network or Building Site License, you will find the instructions on the back of the license.

Minimum Requirements


The Digital Frog 2.5(a) can receive updates directly from the internet.

If you have an active internet connection, The Digital Frog 2.5(a) will notify you of any updates to be downloaded. Updates, if any, will be downloaded automatically and placed in System folder:Preferences:cache-cache:The Digital Frog 2.5.


The Digital Frog 2.5 does not ship with a license to run on a network. A network license must be purchased from Digital Frog International or one of our distributors.
