vpsupd.exe and avast! Free V7.0.1473

Hello!

I have installed avast! Free V7.0.1473 successfully on a Windows 2000-PC without internet connection.
After starting of vpsupd.exe I get a message that I must update to the latest version.
But avast! Free V7.0.1474 has a problem with this “old” OS (Behavior Shield and Script Shield), so I choose 1473.

Can I start vpsupd.exe with a special uncommented “switch” (or flag) to perform the VPS-update with 1473?
