no custom installation of 3.5.5 possible

after system crash (upgrade from win 7 starter to ultimate) i tried to install LO 3.5.5 (14 July), custom installation with additional language support. that was not possible; typical went well instead.
I like LO & have been using it for > 1 yr., but am somewhat under the impression you regularly promise more than you can keep. Microsoft products ARE more reliable, sorry.
