The way that I recommend you do this is to ask the tool for its version via whatever IPC mechanism you use to talk to the tool in the first place.  This avoids you having to code knowledge of the file system layout into your client.  BetterAuthorizationSample shows the basic idea (search for kSampleGetVersionResponse), although it doesn't use the resulting info to drive an update.
