Flash Player EOL for Standalone flash applications

First of all, I don't know how this type of stand-alone applications have implemented their use of Flash. Maybe there is some standard approach that could allow for some standard answer, maybe it varies.

If the application developer does not provide this information and/or updates (or is just not around anymore), or if it's just too important to leave it to chance, I would suggest that you set up a test machine, install the "preview" of Flash removal update that Microsoft made available for testing purposes and then test the applications that you are interested in to see how they work.

To also take into account that newer Adobe-provided Flash versions (32.0.0.371 is a version number that floats around in discussions) allegedly have a corresponding "time bomb", you may also want to set the system date into the future for your testing, to take into account that a Flash player included with the software could potentially still stop working at the EOL date.
