Of course, you will have researched that error code and been flummoxed by what you found - "The installation was cancelled by the user" because there is no interactive user present who could cancel the installation.
I'd bet my last pound/dollar that, because you haven't specified a log file, the installer is defaulting to the location of the installing EXE, to which the account you're using has no write access.
Use the "-f2" argument to add a log file. Remember that, because the original IS developers had no clue how to properly parse text strings, the path *MUST* immediately follow the argument, as in -f2c:\temp\somelognameorother.log
