Dragon Installation Guide
Upgrading with msiexec.exe
Note: When you use the msiexec.exe installer to uninstall Dragon from a command prompt, the
installer automatically retains user profiles from the previous version of Dragon. After upgrading, users
can upgrade their local (non-Roaming) user profiles when they start Dragon. To upgrade Roaming user
profiles, see “Upgrading Roaming Users” on page 84.
The table below lists GUIDs that you pass to the /x option of msiexec for each version of Dragon and Visual C++
Runtime for Dragon.NET framework 4.5. Make sure to use the /x option with the GUID.

Note: See “MSI options for Dragon installations” on page 118 for details on the MSI options available for
Dragon installations. For more information on MSI options, see the Microsoft website: http://msdn.-

To upgrade with msiexec.exe:
1. Open a command line window as an administrator (see “To open an elevated command prompt:” on page 62).
2. To uninstall the current version of Dragon with msiexec.exe, pass the installer the /x option followed by the
old version’s GUID (shown in the table above) and the /qn option to turn off any GUI.
For example:
msiexec /x {33EA20FB-5389-4938-BA59-2BCD9BB68F41} /L*v "C:\updatelog.log"
/qn
Include /L*v "C:\updatelog.log" if you want to create a log of the uninstall and/or update process. You
can change "C:\updatelog.log" to a different location or file name.
Caution:
The first time you run an installation from the command line, you should use the /qf option rather than /qn.
This allows you to see prompts that help you determine any problems with the command line.
3. Install the new version of Dragon with msiexec.exe by passing the installer the /i option followed by the
name of the Dragon .msi file and installation options you want to include.
l For a major upgrade, pass REMOVEOLDPROD=1. This tells the installer to look for previous versions of
Dragon and uninstall them. If no previous version of Dragon is found, the installation continues. In addition,
pass DEFAULTSINI and set it to the full path to your modified nsdefaults.ini file. For example:
msiexec /i "Dragon 14.msi"
SERIALNUMBER=#####-###-####-####-##
REBOOT=ReallySuppress
INSTALLDIR="C:\Program Files\Nuance\NaturallySpeaking14"
