Well, there is the clue right there: the path to the "program" you want got truncated at the space. Just as you do on the command line you need to quote parameters that include spaces and similar interesting characters. One way to do that is:

system(qq{start "C:\\Program Files (x86)\\Microsoft LifeCam\\LifeCam.e
+xe"});
