It depends upon the version.
If you are using one of the older versions, you can use the unins000.exe with the /silent and /norestart parameters.
If you're using the current version (828 is what I have), the install.exe is simply a wrapper for the MSI files. Once installed, you can use standard msiexec parameters for the uninstall. This works for me:
msiexec /x "{FD8C1365-2229-4F37-A126-558DB2471CBE}" /qn
If you find it is restarting you can add a /norestart
