Even passing the log option into the MSI command line,
(both the MSI and IA part of the command line)
I get absolutely no infomation until the main installation actually begins.
In this case, I believe that the installation is failing BEFORE we get to the main install, either due to failing to install prereqs or incorrect command line parameters.

Unfortunately this means the there is no way for us to tell what the issue is.

The MSI wrapper logging just shows a successfull install, and there is no log at all for the IA part of the installation.
Please Help, how can I find out what is failing.
Can I manually write information to the log file?
Cheers
