DocuFlow is delivered through the Documizers download portal as a so-called self-extracting executable. This means that it is an .exe file, but you can extract it via a program such as Winrar. DocuFlow's .exe file contains two .msi (Windows Installer) files, a .bat file and a settings.xml file. The contents of the bat file contain the appropriate command-line instructions.
Make sure both .msi files and the settings.xml file are in a local folder, for example C:\Temp\DocuFlow\
Launch both msi files from the command line with the switching options /i en and /passive.
