Please follow these steps:
1. Download the plugin or estimand to your own computer on your Windows side.
2. Right click, go to properties, and then on the general tab, at the bottom, if there is a button captioned "unblock", click on this button. If not, no worries.
3. If a plugin, place the file into the following folder:
--if using AMOS version 23 or lower:
C:\Program Files (x86)\IBM\SPSS\Amos\23\Plugins (in this case, 23 is the AMOS version number)
--if using AMOS version 24 or higher:
C:\Users\{username}\AppData\Local\AmosDevelopment\Amos\{AmosVersion}\Plugins (make sure to replace username and AmosVersion with your own local directories)
4. If an estimand, you can place this anywhere and it should work fine.
