Cannot install Teamviewer

[dataworx22]

I'm running Knoppix 6.7.1 with persistence, off a USB stick on an Acer Aspire 5520.
I downloaded the 32 bit Teamviewer from here:

http://www.teamviewer.com/en/help/36...tribution.aspx

to my Knoppix desktop. Clicking on the installation folder launches Synaptic, but nothing happens once Synaptic has launched and I can't figure out what to do next.
I issued the following:

knoppix@Microknoppix:~$ sudo dpkg -i teamviewer_linux.deb
dpkg: error processing teamviewer_linux.deb (--install):
cannot access archive: No such file or directory
Errors were encountered while processing:
teamviewer_linux.deb

I also tried Synaptic>File>Add downloaded packages, but the .deb file is greyed out when I find it on desktop. Have I downloaded the incorrect package?
