After downloading the plugin installer from the AppStore, you encounter one of the following situations:

1. You double-click on the plugin and nothing happens or you get an error message. 
2. The installation wizard pops up, but the correct Studio version is not present or grayed out
3. You are prompted to enter your admin credentials in order to install it

For symptoms 1 and 2, follow the below steps:

1. Close Studio
2. Go to the following path (you can copy-paste the path directly in Windows Explorer):

• For Studio 2022: C:\Users\%username%\AppData\Roaming\Trados\Trados Studio\17\Plugins\Packages
• For Studio 2021: C:\Users\%username%\AppData\Roaming\SDL\SDL Trados Studio\16\Plugins\Packages
• For Studio 2019: C:\Users\%username%\AppData\Roaming\SDL\SDL Trados Studio\15\Plugins\Packages
• For Studio 2017: C:\Users\%username%\AppData\Roaming\SDL\SDL Trados Studio\14\Plugins\Packages
• For Studio 2015: C:\Users\%username%\AppData\Roaming\SDL\SDL Trados Studio\12\Plugins\Packages

Note: If you can't find the path above, open Windows File Explorer, click on View and check "Hidden Items" checkbox - Showing hidden files, folders and extensions on Windows operating systems (sdl.com)

 3. Copy the downloaded plugin in the above location
 4. After these steps the plugin should be installed 

For symptom 3, ask your IT department to provide admin rights (username and password).
