Can you look in the windows logs to see if there is some sort of exception that windows is covering up? If you want to know how to do that, simply hit the windows key, if you have one, and type "event viewer".

Then look under "windows logs" and select "Application". 

From there, right click on Application and select Find. Look for "ProSeries" in the log and look to see if there are any errors. 

If you see any on the workstation that look like they could be associated with the network installation, try to right click on the error event and choose "save selected events" to your desktop. Then send them to ProSeries_Engineering@intuit.com. 

Or you could try to attach it here, but i'm not sure how well that will work. Haven't tried that before. 

Let me know!
