this thread looks outdated. anyway..
for me the best solution is wine. file juicer generates a bunch of useless folders and files.
with wine you can use the exe installers as you would do in windows (for example it makes subdirectories as the original installer does)
it creates a folder with windows stuff so you can easily install files there. then you just pick up the files from the "windows" directory and put into your regular sc4 plugins.
it works well with bats but i was unable to install any tool such as terraformer or the lot editor, if anyone got it please pm me and explain how!
