If you need to perform a 'silent' install of Flashback Pro 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 Pro. It just improves performance on older PCs.
If you are using FlashBack Pro and also want to pre-install the licence, you need to copy an XML file we supply to a particular folder. Contact support@flashbackrecorder.com with your licence details for the XML file.
