You would like to know what components are required by Passolo for offline installation since you would like to install all prerequisites before installing Passolo itself, or you would like to build a custom installation package that includes all prerequisites without downloading from the Internet.

The following is the list of components required for Passolo offline installation. If these components are installed prior to Passolo installation, the Passolo installer will not attempt to download any missing component:
