It is because the Exec runs every time and has a signaling relationship
(designated by ~>) with the service. (And note that the Service's
'require' of the Exec is redundant.) An Exec changes state from "not run"
to "run" when its command is successfully executed, and that triggers an
event to be dispatched to any listeners. Services restart if they receive
events, which Puppet by default implements by stopping and then starting
the service.
The best approach would probably be to package the install program and
anything else associated with the service into an installable package (i.e.
an .msi file) and have the Service depend on the package instead of
directly on the installer program. If that's not feasible, then you can
use one or more of the Exec's 'onlyif', 'unless', and 'creates' parameters
to instruct it whether it should execute the main command on any given
catalog run.
