--- Comment #3 from Dan Kegel dank@kegel.com 2007-10-22 06:28:01 --- No need to run winetricks mdac28. Running winetricks native_mdac and then running the app's installer twice suffices. App's installer still fails on .net 1.1 install, but I worked around that by rerunning just the part that failed with native dcom. It then crashes on an actctx problem, sigh.
I'll file a new bug for the .net installer problem.
