Here are some tips on how you can get through older inaccessible iZotope installers using the command line. These have been tested on Windows. If you're a Mac user who can try these tricks in Terminal and report back, please let us know what happens via RWP, the Reaper Access WhatsApp group, or email scottchesworth@gmail.com so I can update the document. Credit for initial discovery of this method goes to Parthy Siva. Robert Hänggi followed up by accessifying a list of parameters from the installer's unattended help documentation (coming up later). Scott is throwing it altogether in one place and clarifying a few points as he goes. Method 1: Easy Generic Install. FIRST, You need to navigate to the directory where the .exe file is in command prompt. To change directory, use “CD C:\DesiredDirectory” Then give the following command, replacing the relevant filename and without the quotes. "setup.exe --mode unattended" The installation will start and after sometime, it will complete silently. The total time until completion will depend on what you are installing and how your machine performs. If you want a visual progress bar in case it helps to know when it is done installing, use the following command instead: "setup.exe --mode unattended --unattendedmodeui minimal" To simplify this process if you don't spend much time in the command line, Parthy recommended the following: I usually rename the setup file to something simple like nectar.exe, create a folder called Temp on my C drive and move the installer I'm going to run into the Temp folder, all done in Explorer as per usual. Once done, the commands I need here are something like: “CD C:\temp” “Nectar.exe --mode unattended” Or if I want progress, then the second command would be: "nectar.exe --mode unattended --unattendedmodeui minimal" Again, always without the surrounding quotes. Method 2: customize your installation with additional parameters. Using the --help switch opens a (somewhat inaccessible) window. Here's the content for Ozone 9 Elements 9.1.0.
