Hi...
Here are a couple of things to try:
1. Make sure you are signed into the Reallusion Hub with the same account used to purchase Character Creator 3 Pipeline.
2. In the Reallusion Hub click "Refresh" to see if the CC3 installer appears.
3. Try signing out of the Hub and then back in.
If none of the above allows you to install Character Creator 3, please visit your Reallusion Account > Registration page using the link below where you will find a Download link for CC3. Please download and install using this installer. If that is successful you can return to the Hub to install the Pipeline Extensions and any Plug-ins you have.

I hope this can help you.
