Formerly called "T4 TimeSaver" Avantax has no documentation for deploying this silently. Right-click eForms2013Setup.exe, Run As Administator. Click Next on the Welcome screen. Use something like Everything Search Engine from www.voidtools.com to find the temporary folder with "AvanTax eForms 2013.msi" and copy its contents somewhere. Use Orca or InstEd to modify the 1033.MST transform file. Change INSTALLLEVEL to 101 for Workstation install or 200 for "Network Administrator" install. MSIEXEC with /qn switch will now work to install silently with the transform applied. Can't register with the CD key during install but is on first startup. You can pre-supply the authorization code by putting "T4Net 2013.INI" in "%programdata%\AvanTax eForms 2013\System Settings" which is a text file with the following section where XXX is your code from Avantax: [Authorization] Number = XXX
