I need two Arduino installs on one machine

I’ve tried downloading the zip version of Arduino but when I launch Arduino it uses the app\local\arduino15 folder and picks up everything from my production Arduino install.

Is there a command line switch to point to another location?

Hi,

If you create a folder called “portable” I think this is what you are looking for

Perfect! Thanks
" From now on all the sketches, libraries and additional cores will be installed in the portable folder. You can copy the whole main folder and bring it with you anywhere you want: it will retain all your preferences, libraries, cores and sketches."
