--- Comment #28 from wine-bug@gigawatt.nl --- (In reply to Anastasius Focht from comment #27)
you're right, nothing was fixed here.
Something was fixed. I noted in bug #22726 that after that one was fixed as well, I was able to install RAD Studio 2007. Wine 1.6 rc4 was the version I'd seen work.
It may have been broken again in a later version, in which case it would be useful to find out which version.
