Other programs not directly compatible with 10.9.2 are ones that require Rosetta as this tip explains:

To find missing applications that belonged to Mavericks without redownloading it, extract them using http://www.charlessoft.com/ Pacifist after downloading and saving the installer to a separate location from the download for Mavericks itself.
Running the 10.9.2 combo update will ensure you have the latest version

once you have extracted the software with Pacifist.
