Yes Blue Prism processes can run in parallel. However, it depends on whether you applications can too. For example, re multiple sessions of the same application allowed, or if 2 processes use different applications, with they interfere with each other? In most situations it's only practical to run 1 session at a time, but if the application allow it (like many mainframes do) then it will work. If however I've misunderstood and you at asking about multiple Windows sessions, then the answer is no, it's not recommended. BP is intended for a desktop OS, and although some clients have tried multi-session, we know it does not scale up - BP was not designed to work like that.
