Debugging Log file

[is11dev]

I create a log file that is created when a user updates their software.

I have compiled about 6 log files from different users and I'm comparing them to figure out why I get the "Software has not properly installed" when installing on a Win7 64-bit machine+. The problem is I'm not sure what everything means. Is there documentation I can refer to that explains what something like:

MSI (s) (A0:08) [10:42:04:884]: Note: 1: 1402 2: HKEY_CURRENT_USER\Software\... 3: 2

means. Or something printing something like signed numbers that mean nothing at first glance like:

MSI (s) (A0:08) [10:42:04:886]: Note: 1: 2203 2: C:\Windows\Installer\in... 3: -2147287038

I can't figure out for the life of me what is going on.
