What does not
Installer displays the spash screen then a grey box after which further progress is not possible.
If installed files are copied from a Windows installation, it does run, and tax forms can be displayed and manipulated, but the main interview/dialog area is blank. It is believed that these dialogs are displayed using HTML but if wine-gecko is installed, the whole thing just crashes.
What was not tested
N/A - it doesn't run.
H&R Block has regressed this product from last year, which ran perfectly.
