--- Comment #12 from Jeremy White jwhite@codeweavers.com 2007-09-13 21:32:35 --- The immediate cause of the crash is in dlls/msi/format.c, MSI_FormatRecordW. The record being duplicated has 0 fields, and build_default_format also returns NULL.
That then leads to an exception, crashing the install process.
It's not clear what the further details are, and why I see this and others don't.
Attaching a +relay,+msi,+seh,+rpc around the relevant bits, as well as a hack I used to get beyond this.
The hack allowed me to proceed, but then the installer got a further crash towards the end that left some processes around.
iTunes seems to be there and kinda sorta works (can't access the store, but...)
