You must insert the plug-in in a container field before you can install or update the plug-in. For more information, see Insert File or Installing plug-ins.
FileMaker Pro installs plug-ins in the following locations:
C:\users\user_name\AppData\Local\FileMaker\FileMaker Pro\13.0\Extensions\
C:\users\user_name\AppData\Local\FileMaker\FileMaker Pro Advanced\13.0\Extensions\
Macintosh HD/Users/user_name/Library/Application Support/FileMaker/FileMaker Pro/13.0/Extensions
Macintosh HD/Users/user_name/Library/Application Support/FileMaker/FileMaker Pro Advanced/13.0/Extensions
Only FileMaker plug-in files can be installed. If a non-plug-in file is located in the target or active container field, no action takes place when the script runs. Plug-in files have the extension .fmx (Windows) or .fmplugin (OS X).
Compressed plug-in files in .zip format or plug-in files in .tar format can’t be installed.
You can use the Get(InstalledFMPlugins) function to identify the name, version, and enabled state of an installed plug-in. This function can help you determine whether the installed plug-in is newer or older than the plug-in required by the solution file. See Get(InstalledFMPlugins).
Plug-ins must be enabled in the plug-in preferences for FileMaker Pro to recognize them. If the Install Plug-In File script step installs a plug-in update but the plug-in is disabled in the plug-in preferences, FileMaker Pro installs the update but does not enable the plug-in. See Setting plug-in preferences.
Note  The system administrator can use the personalization file during a volume license installation to disable plug-ins and prevent plug-in updates from installing in FileMaker Pro. For more information, see the FileMaker Pro Network Install Setup Guide.
