This is what I have in the ini file in the package area:-

Dont remember having any problems with it installing.
What service pack are on your workstations? Stations no longer shutdown when using browse control to automate the command, this is apparent since rolling out SP3!
If you use the original msi you will find it blocks all cd drives on the computers you roll it out to. I have a modified version with the function disabled by default.
