--- Comment #12 from Sergio Callegari scallegari@arces.unibo.it 2013-03-02 05:43:12 CST --- Since all wine stuff with arch set to win64 may install things in "Program Files (x86)" which has a very high probability of triggering the issue, may I suggest defaulting to win32 until this is fixed?
Also please update status to NEW, since this is very easy to verify (e.g. in wine-1.5.25).
