After reading Martin's post I opened Activities>Applications>Other and found several Wine icons that I had not noticed before, I'd been working off the Applications general menu. I was able to open Notepad, Regedit and Wordpad from the icons placed there from the winetricks install (?). They seem to work fine. >From this I think Wine is working OK. So where am I going wrong with SketchUp? I did find some older/other posts on dll's that weren't downloaded or were in a wrong directory/file. The terminal output seems to allude to this (above post code). These were in other versions of Linux and I'm still a little intimidated about deleting and moving files around without some guidance. I will certainly appreciate any suggestions. Dave.
