If your license is activated in the standard node-locked mode (non-floating), you are able to relocate it to another computer only after removing the activation from the current computer. To remove the activation follow this tutorial.
Once the activation was removed, close RealityCapture and sign in on a different computer.
You can check if your license is currently active on any computer here.
Make sure to have enough swaps, otherwise you won’t be able to use your license on a different computer.
If your license has enabled floating, you can close all RealityCapture instances on one computer and use the same license on another computer right away. Noted that when using a floating license, it is necessary to have a permanent internet connection and that it is not possible to use the same floating license on multiple computers/nodes at the same time. Learn how to enable floating on your license here.
The PPI mode is floating by default. You can activate the application in the PPI mode on as many computers as needed using the same account, and it can be used on multiple computers simultaneously.
