|SO lets get this right.|
You hear the stop error but it is never displayed.
Does the software log the install? You should be able to see where it errors out in the log.
If it does not log the install automaticly I would this the installer would have some sort of / command to force it to log.
Without knowing where its crashing out its hard to repair the issue.
I would start by resettng the registry and file permissions.
