If you need a 'silent' install with no user input, you can do this using the command line parameters below.
<installer name>.exe /S "/D=<path to install to>" /nodriver
The /nodriver parameter means the 'capture driver' will not be installed. The driver is not required for full operation of FlashBack. It just improves performance on older PCs.
To pre-install the licence, so users don't need to enter the key manually, you need to copy an XML file we supply to a particular folder. Contact email@example.com for the XML file.
