Man, I would love a follow up on that critical app. When I started in IT we had a sole dev that kept telling IT things couldn’t be updated and I guess they never challenged him. One day I got sick of trying to downgrade to 32 bit windows and moving pc’s around to for the growing needs of the company while one guy dictated everything has to stay old and shitty. Found out that alot of stuff he claimed could work only on 32 bit windows or server 2003, just needed to be tried on windows 10 or server 2016 and it was fine.

Typical lurker here, looks like this guy has the exact model and he attaches the handle and gently prys on tabs on the top and bottom with a screw driver (you might need a pick to really get it in there) to wiggle it out. https://youtu.be/JDPIXUwR8WA?si=OmDHhtSx0k6CwnCb
