I’m experimenting in Unity and had a previous asset called Pathigen that I downloaded to look at the source code to see if it would help my project. However, it was not as useful as I’d hoped - so I ended up deleting it. Strangely, it seems to keep re-downloading itself into the project after I remove it and I cannot figure out how to get rid of it for good. Has anyone encountered this kind of bug? The asset itself was not built with Unity 5 and was updated, though otherwise seemed to be working.
Well maybe that could be the cause have you tried closing the .pdf and deleting it and trying to launch it?
