I have. I have also tried using extension manager and the plug ins library offered from adobe this is the message I get when I try to load this plugin.
"This extension can not be installed, it requires InDesign version in range of inclusively between 8.0 and 8.0.
there are few issues while seeing your already installed extensions in InDesign under Window-->Extension sub menu.
Still there are few steps that you can try:
1. Uninstall the CC 2015 product.
2. Luanch the Creative cloud desktop, launch Extension manger and close.
Restart creative cloud app or system.
3. Install the CC 2015 product.
It should have the products available at the Extension Manger. For the extension at the InDesign menu, we have this issue already known will update you soon.
