This is information on DD3, rather than DD2/DD-pro, but I've been waiting days for the DD3 app (and several others) tp be processed, so I wanted to post the work around information here until DD3 is on the Apps list, then I'll move this information there.
As is the issue with all of the latest Campaign Cartographer series 3 of products, they are now using the InstallAware installation program, and apparently cxinstallwizard and InstallAware do not get along. However, it is easy enough to still install CC3, and DD3, using a command line work around that is pretty straight forward.
Open up a command line, and then change your working directory to the installation directory of Dungeon Designer 3, then run the following single command:
X_BOTTLE="your-bottle-name" /usr/bin/wine ./DD3Setup.exe
It will start up the installer, and proceed normally from there.
So far initial testing shows that installation is smooth, and starting up the application later on works fine too.
I haven't yet performed heavy usage of the product(s), will be doing so over the next few days, and will report back any issues, or if it goes smoothly.
I am running this on Suse Linux 11.1, using KDE.
