IBM Websphere MQ Explorer 7.5.0.2 - install MSI special command line requirements.

The websphere MQ Explorer 7.5.0.2 MSI installation requires some parameters to be supplied via an ini file.  This ini file is specified on the command line using the USEINI parameter.

msiexec /i "IBM Websphere MQ.msi" transforms=<name> USEINI=<path> /qn

/qn or /q must be used so that the MSI is run with no user interface at all.

important: the USEINI path must be a full and absolute and not relative.  Putting the ini file in the same folder as the MSI/MST and using USEINI=myfile.ini will NOT work.

UNC paths will work.
