heyo y’all. As of recent i’ve gotten this issue where processing 3 (64 bit) will fail to launch after i open it. I’ll include an image of the message uhhhh ![processingisntworking](https://canada1.discourse-cdn.com/flex036/uploads/processingfoundation1/original/2X/3/37b7f04fdfaabcb21e1038ce576f3c505f6080a9.png)

please bear with me because i’m not good at fixing computer issues. uhhhhh I’ve got java installed, latest version and all that, running windows 10 pro, version 1703, i5-7300 cpu @ 2.60 ghz 2.71 ghz, 8 gb ram and i’m using 64 bit. my laptop’s been kinda messed up lately because i hadn’t updated it in like the past two years, it was crashing and all that. finally updated and it’s no longer crashing, though the updates section in settings is telling me i need to update (even though it doesnt and wont let me see the update history). but i’m probably overthinking it, and if anyone could provide me with any advice on fixing this i’d appreciate it a lot \<3
