Problem I'm having is updating versions. We push the software out via Altiris, it's basically just a job that runs "\\DFS-SHARE\mimiostudio.msi /qn ALLUSERS=1" at cmd line. Works just fine. I would be interested in knowing what the /Lvuc is. That command installs Mimio and puts it in the Start/Startup folder, so Mimiosys runs everytime someone logs in. Unfortunately when a new version comes out and I edit the job for the new filename...it won't install because mimiosys is always running in the background and it doesn't seem to kill the process. I've tried a vbscript to kill the service, but it doesn't work. We also don't give our users any admin rights, so they can't run the install as themselves. We have a ticket in on this, though I haven't heard anything for weeks.
I'm contemplating testing a msiexec /u mimiostudio to uninstall it and then, in the same script, run the install of the new version. Just haven't had time to try it yet.
