Slight confusion here.
You have posted in VX Ace, but are now referring to VX. Could you clarify which engine is involved.
If you have transferred just the project, then the only files present in it will be any that you have specifically imported. Everything else e.g. the battlebacks, are in the RTP, which is probably not installed on your laptop. You will have to install it yourself.
Go to the top of this page and let your cursor hover over the 'Download' button. In the dropdown menu, the middle column is called 'Additional'. In that column you will see 'Run Time Packages'. Click on that, select the RTP you want and download it. Then follow the installation wizard.
