I sigh with relief when I see retro installers like that - at least you know it will work!

We have very different memories of the early 2000s.

I distinctly remember hunting down and deleting all the DLLs and registry crap these uninstallers left behind.

They at least appear to hav a proper uninstaller. Many new services nowadays just hide that as a separate exe somewhere deep in their support pages.

Used to use WebEx at work. I hated it.

But I can't remember anything wrong with the installer/uninstaller, really. Don't know why you want to complain about that.

The uninstaller has a UI that is readily understandable, and does what it's supposed to. The rest of the application does not.

What is wrong with that picture?

Nothing is "wrong" with it, the design is just something from the 90s/early 2000s.

as opposed to bloated 2020 minimalist designs that don't work
