This new version supports silent setup now.
Example: daemon408-x86.exe /S /D=F:Some Folder
Note that no quotes must be used in installation path even if name has spaces.
All critical errors will be still displayed no matter silent or not.
Case of parameters is important, eg. /s will not work.
Reboot prompt will not be shown.

If SPTD was not present then it will be silently installed but
PC will not be rebooted - it is assumed the administrator who
performs unattended install will take care of reboot and restarts DT setup after reboot in this case.

It is best first to use standalone SPTD installer and install it silently this way:

sptdinst-x86.exe add /q

Note: SPTD 1.37 will not display debugger warning dialog anymore. They left this info in EULA only as this message confuses many users and also not "silent setup friendly".
Standalone SPTD 1.37 installer is released by Duplex Secure officially and can be obtained at their website http://www.duplexsecure.com

Also fixed:

a lot of Installation problems (f.e. invalid device, prob 12 etc).
SPTD 1.37 fixes also problem reported with virtual drive from InterVideo DVD Copy 5.
