The only variable in this game is the LibreCad version. If the old 2.0.0 runs, but the newer ones don't, then it is reasonable to assume, that something in the newer versions has/was changed. The 2.0.0 has already Qt5.
I looked at the sources of Qt5, and, by jove, a compressed volume of about 500MB does look somewhat like the tower ob bable. As does their EULA :-). But I'll try the portable version, too.
