Thanks for the quick reply. I tried winetricks dotnet20 with my existing Wine installation (no luck), then updated Wine per http://www.noobslab.com/2012/03/install-wine-1.html. I am a little confused by the version numbers - I'm seeing 1.3 and 1.4 used almost interchangeably. In any case, my version is now telling me 1.4. When I tried the builder after that, I got a message about missing a Gecko package. I tried to update that, but the installer crashed midway. It looks like the package is already installed? After that (and a reboot for good measure), I'm back to the same errors. I'm sorry if I'm being clueless here - is there anything else I can check? Thanks!
