Yes, please install the latest version on the source machine. The latest version now supports a way to skip Pro trial in Make. Assuming you are running Windows, you can open this file in notepad:
C:\ProgramData\SketchUp\SketchUp 2015\SketchUp.lic
Then put this exact line as the only thing in the file:
##NoTrial
You can delete whatever might be in the file, replace it with this text and save the file.
Now when you run the program, you should see the Welcome dialog asking you to agree to non-commercial use. If you click “I agree”, SketchUp should then run as Make on the source machine. You should be able to image the machine after this. Sorry about this inconvenience.
