Most of the programs in the Google Pack could be installed without using the Google Updater program, but there is three one exceptions: Spyware Doctor Starter Edition, Norton Security Scan and Google Photos Screensaver, you can’t install any of these this programs without using the Google Updater program.
The version of Spyware Doctor that you could download from the Spyware Doctor website is limited to only scanning your computer, but not removing spywares.

But there is an solution, I used the Freeproxy program to sniff the connection, and set the Google Updater to use this proxy server when downloading the programs. I enabled the logging of all connections so that I could get the direct download link to the setup files.
The download links to the different programs are is:
Spyware Doctor Starter Edition v7.0.0.545 (Multilingual) (alt)
Spyware Doctor Starter Edition v6.0.0.362 (Multilingual)
Spyware Doctor Starter Edition v5.5.0.204 (Multilingual)
Spyware Doctor Starter Edition v5.1.0.272 (Old version) (Link still working)
Use the last download link, if the first doesn’t work. (Just update it afterwards).
Norton Security Scan v2.0.0.87 (English version)
Norton Security Scan v1.3.0.26 (English version)
Norton Security Scan v1.3.0.26 (Norwegian version)
Google Photos Screensaver v2.0.0.1077
