There's nothing like having a locally installed program that has no internet dependencies for reliability. There's a reason machine shops still have that one PC running MS-DOS 5.0 in an emulator. The tool built in Tk!Solver version 1 in 1982 can't be easily replaced, and it's required to compute bevel gear generator setups.
Changing anything in the setup might cause gears to come out wrong, and cost thousands of dollars in scrap, and the loss of a customer.
When you have a locally installed program, offline, you're pretty much immune to most of the troubles of the technical world.
