Woops. And 64 bit

Ubuntu 9.04. Wine 1.1.39

Ok, I ran ./winetricks and winetricks started. It shows a list of possible programs to install. Sketchup is not on the list.
So, what now? Please...
Thanks.

I installed winedoors and it installed sketchup. But on installation, winedoors froze up.
Now, to install winetricks I went to...
http://ubuntu-snippets.blogspot.com/2008/05/as-most-of-us-know-wine-is-used-to-run.html

I ran these commands as instructed...
wget http://www.kegel.com/wine/winetricks
chmod +x winetricks

But that is as far as I got. What do I do from there?

Winedoors? Never heard of it. I'll go try to find it and download, etc. It there is any secrets to it, let me know.
Thanks.

My video card is Nvidia...VGA compatible controller: nVidia Corporation G72 [GeForce 7300 SE] (rev a1)

The program did start. It ran to the main menu which offered choices ...1) training videos 2) help center 3) make buildings.

I'm am trying to run it under wine, since I am running Ubuntu Linux.
When I click on either of the offered choices I get an error report window. When I go to the proper file to view the error report I see this information...

Can someone help me figure this out?
I posted this in the Ubuntu forum also, but no help from them. Can someone here help me out?
I was wondering if this is a low memory problem. I have 1 gig of RAM.
