The easiest way is to simply take the installation files for SCS from the SCS CD and copy them to your primary servers client install point, from ClientRemote you can then choose which source you want to use. (You may even already have a folder called Win32SCS present)
Also, if you install SAV Server from the SCS CD (its on there too) then it copies Client Security into the default deployment folder instead of just SAV.
If you do it the first way, just make sure you copy the pki folder from the SAV distribution point and you should be good to go.
Also, if you are still running 10.1.0.394 then I'd recommend upgrading if you can (even if its just getting the patch for SYM06-010)... its now quite an old version and there are several well documented security vulnerabilities with it.
