I was able to find the rendered output by redirecting the place where the file was stored. I now tell vmd to drop the .tga file on the desktop.
Thanks to all for the help.

In windows, VMD's default working directory is C:\Program Files\University of Illinois\VMD , which is where VMD/tachyon is trying to write the file. If you go to that directory, via explorer or cmd.exe, you will not see your file, which suggests that the directory is not writable.
However, if you have, e.g, Gimp installed, and try to open the file (menu file->open...), you will see that your file is there! :)

Perhaps you are running into a windows compatibility "feature" -- the virtual store<>. Older windows programs in the pre winXP era used to write configuration files in their installation directory. But starting with win vista, this was no longer possible by default due to the default filesystem permissions. In order for legacy applications to work semi-correctly, the writes to the program files folder are redirected to a "Virtual store".

A possible workaround is to install VMD outside the program files folder (for example in C:\VMD or something).

Best regards,
