IOPL not enabled error when trying run Excel 2003

[Czubek]

Hi.
I'm trying to run MS Excel 2003 from windows partition and I get error:

"IOPL not enabled"

I'm using:

wine-1.1.4
ubuntu 8.04.1

I have:
WINEPREFIX="/home/czubek/.wine" in /etc/enviroment

It looks here (http://ubuntuforums.org/showpost.php?p=4885918&postcount=12) like winetricks should help but I get another strange error with it:

sh winetricks dcom98

Note: command 'wine regedit /home/czubek/.wine/drive_c/winetrickstmp/override-dll.reg' returned status 1. Aborting.

Someone know what's wrong?

Thanks in advance.
