I have done some more research now but it seems the exact specification is
buried somewhere where at least I can't find it. Nevertheless I have found
some potential reasons for the "Install Program as other User" dialog not
appearing. In the W2k Group Policy Reference there are two pages related
to this:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/gp/337.asp
describes how to turn off this feature using group policy, while
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/gp/338.asp
explains how to enable it even for network shares.
There is (as always?) a registry entry related to the Group Policy:
http://www.tburke.net/info/regentry/GPRef.htm#93546
(should check for Microsoft's documentation regarding this point - but I 
beleive him)

There is also a knowledge base article with the same info:
http://support.microsoft.com/?kbid=310360
Just loosely related but also interesting:
http://support.microsoft.com/?kbid=314855

This clearly doesn't answer your questions where this feature is 
documented and whether it is language dependent but it hints at two more 
spots to look at when it's not working:
- it might be turned off by Group Policy or the corresponding registry value,
- setup.exe might reside on a network share meaning that the "Install..." 
dialog won't show up by default (could verify that behaviour on my machine).

I'll check that out. But you'll have to explain that to me in clear and 
simple words, that even I am able to understand what I am supposed to do.
