Install Plug-In File
Installs or updates a plug-in file from a container field onto your computer.

Install Plug-In File[<table::field>]
<table::field> allows you to specify the container field with the plug-in that you want to install or update. If no field is specified, FileMaker Pro installs the plug-in in the current container field in the active table.

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\14.0\Extensions\
C:\users\user_name\AppData\Local\FileMaker\FileMaker Pro Advanced\14.0\Extensions\
Macintosh HD/Users/user_name/Library/Application Support/FileMaker/FileMaker Pro/14.0/Extensions
Macintosh HD/Users/user_name/Library/Application Support/FileMaker/FileMaker Pro Advanced/14.0/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. In Windows, plug-ins have the extension .fmx (32-bit FileMaker Pro) or .fmx64 (64-bit FileMaker Pro). In OS X, the plug-ins have the extension .fmplugin.
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.
For FileMaker Server-hosted files, the server administrator needs to allow the Install Plug-In File script step to update FileMaker Server plug-ins in the Server Admin Console. See FileMaker Server Help.

Installs the Video plug-in.
Show Custom Dialog ["Do you want to install the latest version of the Video Plug-In?"]

Example 2 
Detects the application architecture, then installs the appropriate version of a plug-in.

Install Plug-In File [Plugins::32bit]
Else If ( Get ( ApplicationArchitecture ) = "x86_64"]
Install Plug-In File [Plugins::64bit]
End If
