if the plugin was previously installed using the Adobe Exchange site, it is necessary for this version to be uninstalled before version 2.4.5 can be installed. Once you have uninstalled the plugin, the CC app needs to sync after an uninstallation so that it removes the CC install folder.
For PCs this folder can be found in the following location:
C:\Program Files (x86)\Common Files\Adobe\CEP\extensions\com.axomic.openassetforindesign.extension
