Is a Docker or a VM solution possible? I admit to not being very knowledgeable here. If you can get a virtualized solution running a different version of Windows (or Linux) on these machines just for your app.

Either that or it's rebuild the app using jQuery and an earlier version of Bootstrap. For an alterative for Electron you can look into LibUI plus LibUI-Node.

That is something a coworker is looking into, the biggest problem is we are expected to have ~5,000+ users of our app internally providing them all with VM's is way beyond the scope of what we support.

Even getting our app running on premise was a nightmare, and resulted in us just buying a rack mount and having them put it inside their DC, after everything they gave us was pretty awful.

Consider perhaps a remote-terminal solution - in general I am against VDI and Citrix and such, but maybe you can find a remote app delivery mechanism that still has a Win2k client and can display the browser running remotely.

There are X11 servers for Windows that might be able to run Electron off a remote Linux machine, though watch out for problems with opening files and copy/paste.

Don't quote me on this, but I'm fairly certain it's not reasonably possible to get a proper VM running on Windows 2000. Even if you can get some form of virtualization working, it's going to be far too slow and cumbersome to run Electron.
