--- Comment #2 from Juan Lang juan_lang@yahoo.com 2010-03-09 14:44:07 --- The bug looks similar to that reported with the Mass Effect installer, bug 18019. Same method of reproducing it, changing the default directory, and both have a NULL pointer violation with nsisdirselect as the bottom stack frame.
The last fixmes (GetProfilesDirectoryA) appear unrelated to the crash. I implemented the function enough to be believable, and the crash persists.
