But currently, if you use the new installing way (from hard drive),
Gecko installs during wineprefixcreate if user has it set up correctly.
It means that some users will have always set IE version, others won't.
It's definitely not what we want. We may consider reverting installing
Gecko from DllRegisterServer to make it at least the same for all.

The real solution is to always set IE version. To do it we have to fix
apps that block it. The problem, apart from that I didn't have time to
make bug hunting on them yet, is that we don't really have a list of
such apps. Quicken is the main example, but who knows what are the
others? It would be great if we had it somewhere in bugzilla or wiki.
