[Wine] Can't install Microsoft Data Access Components

[Nuno]

I am trying to run the program Bioedit in a Mac OS X 10.6.7. I have Wine+Winebottler 1.1.44 and Wineskin Winery 1.1. I can install Bioedit without problems, but when I try to run it this appears:

Error creating object. Please verify that the Microsoft Data Access Components 2.1 (or later) have been properly installed.

So I downloaded MDAC v2.81 from CNET (couldn't get it from Microsoft) and tried to install it. But during installation this message appears:

Fatal Setup Error
This setup does not support installing on this operating system.

I've spent hours in google and forums - it seems that this MDAC installation error is quite a common problem. I have tried several things but nothing seems to work.
Does anyone know of a way to fix this?
Thanks!

Did you try installing it with winetricks?

If so, which version of winetricks?

Hi Dan

I went to the Mac Terminal window and I gave the command:
curl http://winetricks.org/winetricks > winetricks

To confirm the installation I asked for the version:
sh winetricks -V
it gave me '20110429'

Then I wrote:
sh winetricks fakeie6 mdac28
but I got the message:
"wine cmd.exe /c echo '%ProgramFiles%' returned empty string"
(I also tried sh winetricks mdac28 - same problem)

I have no experience whatsoever with UNIX and shell scripts, though. I followed tips that I found in different webpages. Am I missing something?
