Your patch fixes the issue, applied to the latest git: Wine-1.1.41. I've tested several game demos that use Installshield and now they work.
It's a pity Wine-1.1.41 came out before the patch was committed, because the bug prevents a lot of apps/games from installing correctly that use Installshield. Isn't there an option to release a modified version like 1.1.41.1?
It's a development release, things are often broken. 1.1.42 should be out in two weeks, so either use 1.1.40, patch 1.1.41 manually, or wait for 1.1.42 (assuming this patch makes it in).
