Something quite interesting. I found in the office another system with Lucid 10.04, the same wine version (1.1.42). I placed the CD, ran the setup.exe and it opens the installation window!!! This system already has office 2007 installed. So I looked into the cfg file of wine, and found in the libraries the following "Existing overrides:" gdiplus (native) msvcrt (native, builtin) msxml3 (native, builtin) riched20 (native, builtin) riched32 (native, builtin) So I went back to my system and using "winetricks" I downloaded these libraries. When I checked in my cfg window, all these libraries are now there but their names have an asterisk, e.g.: *msxml3 (native, builtin), etc. I put the disk in the drive and again, the problem remains. My question is: what could make the difference between these 2 machines? Thanks, Daniel
