--- Comment #2 from Anastasius Focht <focht at gmx.net> ---
Hello folks,

confirming. The installer targets Win9x-based systems and the check is simply
broken/non-applicable on modern Windows NT based OS.

The brain damage:

Again, this can't work on native Windows NT based systems.

You can work around in Wine by setting an app specific dll override for the
sub-installer to prevent loading of 'shell32.dll' at all. It will then
successfully install the old IE 3.x crap.
It needs to be app specific override to ensure that Wine builtin/main app
processes can still load 'shell32.dll' (otherwise they would break earlier).
