First step is to log into C2C. You should see a warning telling you that they need to install the Practice Middleware.
Click on it and then press "Get Practice Middleware".
After installation, open up the shortcut on the desktop and sign in.
By minimum you need to set up the Archive, Scanned Documents, and Errors Folder.
Create the folder on your C drive as below and link them in the practice middleware.
If the machine is a pathology downloader, you can create and link that folder too.
