I'm trying to set up a test environment to prepare update BusinessVision 2018

I'm trying to set up a test environment to prepare update BusinessVision 2018. I install v7.90 on a new server and copy data folder to the new server. However, when I amend company and open bvcon.fil file, I got an error: multicurrency license file is damaged or no found.  I didn't find the function of register the license from license manager.  How can I fix?
