ADF1999.02 is a minor upgrade of ADF1999, primarily to solve a few installation problems and to extend the number of supported platforms. For several platforms already supported by ADF1999 no executables have been replaced. The source code at the web site corresponds to ADF1999.02
There is also new functionality: ESR properties. However, to use this you don't need to download ADF1999.02, as the functionality already exists within ADF1999. It is documented now in the ADF User's Guide. If your current ADF1999 license file denies you access to the ESR feature, contact us for an upgrade of the license file.
