The 3rd party software ("WhenU") gets nuked by Symantec Antivirus Corporate Edition v10.x upon install; it's identified as "malware". I assume this is true with other AV-solutions as well, so no need to specifically remove the 3rd party software.
Installing in this method will also install the third party software. I have not identified a way to install Daemon Tools 4.x without the third party applications.
for silent install with sptd driver but without gadget
DTLite4454-0315.exe /S /nogadget /sptd
(sptd install is not completely silent)
Then modify registry to deactivate mountspace statistic:
[HKEY_CURRENT_USER\Software\DT Soft\DAEMON Tools Pro\Config]
to hide the mountspace sidebar:
[HKEY_CURRENT_USER\Software\DT Soft\DAEMON Tools Pro\Options]
