Starting from the build 2020.1.161, you can customize the output folders for samples and Eyeshot assemblies by using an optional INI file.
How to proceed
1. Download the eyeshot installer in a folder (e.g. C:\Installers).
2. Create an INI file (e.g. setupvars.ini) in the same folder and edit it to specify the custom directories.
The INI file must be in the following format:
%AppFolder%="C:\CustomFolder\Eyeshot Ultimate 2020"
3. Open a command prompt and run it with /S option specifying the path for the INI file
(e.g. "C:\Installers\EyeshotUltimate20201161.exe" "/S:C:\Installers\setupvars.ini").
