A relative's business has been and is still completely driven by a VB app. It's goddamn ugly but most businesses of their size in that industry have been paid subscribers for 30? years at this point. Most notably its the only piece of software they've never had to ask me for help with at all.

The only updates it gets anymore are little data packs when laws/regulations change and it seems like they automated that because it's always ready before it's needed. The last "big" update was a guide to running it in parallels on new macs.
