Unable to update the testcomplete to version 15.0

HI,

We are using TestComplete on multiple machines - 

Machine A - License Manager Machine (v14.93)

Machine B - v14.93 - floating user license

Machine C - v15.0 - trial version

Using Machine C project has been created and when user from Machine B tries to open the same project in his machine then he won't be able to open the same and getting following error - 

If we try to update the version of TestComplete in Machine B to V15.0 then user is getting following message - 

As User from Machine B is using the floating user license and didn't have the credentials. 

Is there any solution for this particular scenario
