If you try to run an executable you are asking the operating system to
locate the image, load it into memory and begin execution. The system
cannot know anything about Tcl's virtual filesystem and therefore
cannot load an image from it.
You must copy such images out of the vfs and into some location on the
native filesystem and run them from there. /tmp or $env(TEMP) is best.
