Transferring Pro to a new computer or licensing multiple
computers  A Single-user license is associated with one person.
That individual can install the license on any computer he or
she is using, but only one computer can run SketchUp Pro at a
particular time. To use your license on another computer, or
transfer your license to a new computer, please note the
following steps:    1. Install SketchUp Pro Trial on the new
computer. Please visit the download page to get the install
file.   2. Use your Single-user license information to authorize
it.   3. If you're no longer going to use SketchUp Pro on the
original computer, you should uninstall it.
