Hi, Katalon community,

I would like to ask about the **Floating License of the Katalon Runtime Engine**.

Let’s assume this kind of environment:  
Two machines, each in its own environment (different networks).  
Machine A in environment A and machine B in environment B.  
Both machines will have installed KRE.

Will I be allowed to execute tests on machine A and once these tests are completed, run tests immediately on machine B using the same license?  
Or will I be allowed to run tests on both simultaneously?

Thanks a lot  
Kind regards,  
Tomas
