Is keyshot 2 completely independant ie do I uninstall version 1 before installing version 2 or I leave things as they are and run v2 as an update?
How Uman says, both work independently.
In other cases, I personally recommend always (Windows):
- Uninstall,
- Clean up
(Ccleaner) or similar...
- Installing the new version/build/release...
(With Linux and OS X not necessary, in most cases)
