Hi,
Currently, the NVivo update process uninstalls the product and reinstalls the new version. This requires the IT admin to add a pre-script to deactivate the license and a post-script to reactivate the license. Instead, you should use the NVivo official update designed for this purpose. See the following link:

But with our tests, it seems that the correct command line to install the update is :
Update.x64.exe /S /v\"/qn REBOOT=ReallySuppress\" /clone_wait
Thanks
