--- Comment #5 from markk@clara.co.uk 2008-07-01 19:29:14 --- This issue affects a huge number of older setup/installer programs. While the resulting error messages are non-fatal in some cases (i.e. the user can manually run the installed program afterwards), in many others the installer aborts. That's a shame because Wine would probably be able to run most of the programs fine.
