Captivate 2019 Update 5 fails and corrupts installation

The installation of the update fails near the end and seems to corrupt the installation. When I start up Captivate 2019 I get a dialogue box that reads Adobe Captivate 7 The localized resources files for this application could not be loaded…… After I click OK the Captivate 2019 splash screens displays but then disappears. There is no option to repair so I have to uninstall/reinstall. I didn’t see any solutions so any suggestions would be appreciated. Dave
