I just installed Ubuntu 6.06.1 LTS on a new laptop for my dad, again. I hadn't updated Crossover on his previous laptop so I took this opportunity to get the latest version (5.0.3).
In order to install Dreamweavers UltraDev 4 on this system I first installed DCOM95, then a minimal IE6 install. Trying to install as the supported "Dreamweavers MX" and trying to use the "Unsupported" install checkbox both failed immediately.
However, I used "Run a Windows Command" from the Crossover menu, and used the browser to choose "UltraDev 4 Installer.exe" from the cdrom, and it installed itself quickly and easily. This time the Wine instance didn't hang or anything, and there were appropriate menu items added to my Ubuntu desktop menus.
Sweet!!
