--- Comment #9 from reuben.m@gmail.com 2008-07-12 02:21:17 --- By crash, I simply mean the window disappears and nothing seems to have been installed. None of the install files are cleaned up. It just seems to stop right in the middle of the install after extracting the msi file.
I set WINEDEBUG=warn+all and dumped sterr to a log file. Perhaps you can sift through all that garbage and get a better idea of what is going on.
