Complete installation instructions for all HELIOS products can be found in the HELIOS Base manual.
The “HELIOS Applications” volume contains all installable applications that are part of the HELIOS product suite. The volume always contains the latest versions of the applications. If you install any HELIOS updates by means of the update installer, the contents of this volume will be updated automatically and the items in this volume can then be used to replace older copies of the applications that exist on the local hard disks of your Mac client computers.
Refer to the “README.txt” file (“HELIOS Applications > MacOS > PDF Tools > Acrobat Plug-Ins”) for installation details on different Acrobat versions.
