I havent found a way to automate the install of the main Insite application, but when you download updates they are temporarily stored in c:\programdata\cummins somewhere, just do a dir /s *.exe
Copy the .exe file out of there and it can be installed outside of the update manager by using the following switches.
If you don't use those switches, it will say that you must install the update with the update manager.
If you want a fully silent install do deploy with something like SCCM, use:
Update7_06_1_195.exe /V"UICMDLINE=/UI" /S /v/qn
