I just bought a new pc with a better graphic card for Reallusion Softwares. I have two questions, or rather one question and one problem.

1. Can I use a single license for IC7, CC3, CA4 and CA5 on two PCs i.e. I have it already installed on my laptop and now I want to use it on my tower pc as well without buying a new license? I'll be using one pc at a time.

2. So here's the problem. I have copied my custom and template folders from my old pc to the new one. There I want to install the software on NVme C drive but want tho programs to keep/access template and custom folders on SSD drive I. When I install CC7 and CC3 through RL Hub, it doesn't give me the option to choose location of custom folders.
For IC7, I found a workaround. After uninstalling IC 7.9 and Hub, I installed a previous version IC 7.8 and it asked me where I want to save the program as well as the location for template and custom folders separately. So I installed the program on C drive but for template and custom folders choose I drive. Then installed Hub and updated IC 7 to the latest version 7.9 and it works fine so far and I can see all my custom content in gallery.

But this method doesn't work for CC3. I can't download a previous version of it from RL site. It can only be installed through Hub. When I ask it to install CC3 to C drive, it doesn't give me further options to choose the location of template and custom folders and automatically creates those folders on C drive. How can I install it in a such a way that CC3 installs on C drive but it can access templates and custom content that I already have on I drive? 

I don't trust methods like editing registry as it can be risky. I just want a simple and stable  method. Can I download a previous version of CC3 that can be installed without Hub and allows me to choose the location of custom content.
