This may be a silly question but where can I find the autoload.php file the shared.php is calling for saleforce workbench. I have been running version 43 for the longest time and went to upgrade to v50 and I keep getting errors about autoload.php. Searching on the internet brings me to composer and I have installed that as well but still face the same error. I tried commenting out the call and creating a blank autoload.php file both just caused other errors. Running xampp setup.
