I'm not sure if this is possible, but it would be nice if the installer would fill the installation path from Download Runtime wizard.
The same for runtime detection after the download and installation is finished.
1. Select JBoss DV 6.1 for download&installation
2. On "Download Runtime" page of wizard fill some install folder (for example /home/<user>/downloadedDV)
3. Click Finish - DV is downloaded and it's installer executed
ASSERT: /home/<user>/downloadedDV is default installation path in installer
4. In the installer select different installation folder (for example /home/<user>/DV)
5. Finish installer
ASSERT: /home/<user>/DV is added to runtime-detection paths instead of /home/<user>/downloadedDV
