As you may be aware, Apple has released macOS 10.15 Catalina. Apple has made the decision to drop all 32-bit application support with this release, which impacted EndNote X9 for Mac and in the end also EndNote X9 for Windows. You can read more at Apple’s knowledge base article here: https://support.apple.com/en-us/HT208436.
Starting with EndNote X9.3.x if your end users open a library, EndNote will ask you to convert your library to the new X9.3.x format. Although the existing library will not be touched, it is wise to prepare for the conversion to avoid any conversion hiccups BEFORE UPDATING OR UPGRADING ENDNOTE TO VERSION X9.3.x. Read the recommended pre-conversion steps here.
