In order to use vpsupd.exe, you must always use the latest version of the program.
Now, the latest version of the program is 4.7.1043 (but it seems you're using version 4.7.1001).
Please update to the latest version by downloading its setup package and running it on the machine in question (this will work if the machine is not connected to the Internet, which I suppose is the case here as you're using vpsupd.exe to update the virus database).
Cheers
