320	cooperation with Windows Vista's User Access Control	Toxaris		"Installation of a cabal package under Windows Vista with UAC activated may fail even when working as administrator, because cabal doesn't request the necessary rights to write to, e.g., ""c:\Program Files\Haskell\<whatever>"". A workaround is to start an ""Administrator console"" to start Cabal from a process which already acquired admin privileges.

Cabal should request the necessary rights instead of failing.

cabal-install should check in advance whether the target destination is writeable and fail early or request the necessary rights. (currently, cabal-install fails after compiling all dependencies. After starting cabal-install again from an Administrator console, everything has to be build again).
