How can the SVS Agent be upgraded on my clients?
Upgrades of the SVS Agent can be accomplished through standard Windows Installer methods. The product key is validated each time the install runs, and, therefore, must be provided.
In order to do an upgrade, you need to provide a new .MSI file. You also need to tell Windows Installer to recache the installer package using the new file (the v switch on REINSTALLMODE does this).
msiexec.exe /qn /I Software_Virtualization_Agent.msi REINSTALL=All REINSTALLMODE=vomus PRODUCT_KEY=<product-key>
