Question

Would it be possible to put install THG on a shared drive and let
users run it from there without having to install it locally on each
user’s machine?

I’d be willing to accept some minor loss of functionality such as no
overlay icons or menus in Explorer. Maybe people can only use the
workbench interface…

Bonus points if the local stuff could be wired up after it was
installed centrally!

Answer 1

I got an answer from the TortoiseHG mailing list:

There are two things you miss by not running the installer:

1. Explorer extension (context menu, overlay icons)
2. Having the apps in your PATH (thg.exe, hg.exe, kdiff.exe, tortoiseplink.exe)

The workbench and other apps should run just fine from a copy of the
install folder.
