QGIS Standalone installer suggests a default installation location like c:\Program Files\QGIS Wien, including version name in the path. Does this mean the recommended way to update to a new version would be to uninstall the old version, and then install a later version? Or can we just as well install a newer version on top of the previous version? (in which case it makes more sense to change the location to e.g. c:\Program Files\QGIS).
Answer
Although the other answers provide useful information, I'm adding my own anser to address specifically the question of the install location:
Major QGIS versions installed via standalone installer on Windows are identified as separate programs (e.g. QGIS Essen, not just QGIS), so they should not be overwritten/updated in-place. (While the program would probably run - I tried - you might run into problems, and it also messes up the software registry because now Windows thinks there are two programs installed in the same location).
As Jochen's answer indicates, installing multiple versions via standalone installer (in separate directories) should just work. I haven't seen any problems with it, though risail's answer says you might run into dependency issues.
