Hello Qristian,
For Sprite-O-Matic you need to follow below steps:
The ZIP(spriteomatic.zip) will appear in your local Downloads folder on C drive. Unzip the file.
Copy/Move the script file (Sprite-O-Matic.jsx) to your After Effects ”ScriptUI Panels” folder.
PATH: /Adobe After Effects CC 2015/Scripts/ScriptUI Panels
Once installed, you will be able to run this script from the WINDOW menu in After Effects.
Compatibility: This product is only compatible with After Effects CC (2017) 14.0
For Squash and Stretch Free it should automatically appear in Windows> Extension, once you install the add-on via the creative cloud on.
Request you to kindly try to follow steps:-
1. Please reopen the CC Desktop App, then please can you log into https://creative.adobe.com/addons/my_addons.
2. Then click on ‘Remove’, then ‘Install’. Please wait a few moments, then wait for the pop up in the CC Desktop App, and confirm if it states that installation was successful, or failed?
3. If it failed, please provide us with the exact error message and its screenshot.
4. If it says successful, please read the ‘Where to Find it’ tab on the add-on homepage (link above) which will tell you where you can find the product after it has been installed.
5. Restart the After Effects.
6. Also please make sure that file sync is on in CC app and you have logged in with the same adobe id (from which the add-on was purchased) in CC desktop app and https://creative.adobe.com/addons/my_addons.
Hope this will help. If you still face the issue in any of the above extensions please contact us asupport@adobe.com
