I have multiple versions of processing installed. When I try to open processing 3, the PDE that opens up is processing 2. Similarly, when I try to open processing 4, the PDE that opens up is processing 2. Strangely, multiple versions worked before (I was able to run processing 3 and 4). Any ideas as how to fix this? Thank you.
Make sure you don’t have a “ghost” Processing 2 process running (check task manager), as Processing will always start up in the version of a currently running instance (see Can't have Processing 3 and Processing 4 open at same time · Issue #244 · processing/processing4 · GitHub).
