Installing the Demo version while keeping the previous full version

[malage]

Hi,
We are trying to install the demo version of Vray for Sketchup, but the installer uninstall the previous full version from the computer. Could we install the demo version while keeping the full version installed and running? We have the full version installed on Sketchup 2014 and we would like to install the demo on Sketchup 2017. We want to try the new features before purchase the upgrade.
Thanks in advance.
Regards.

Go to customize and turn off "uninstall previous versions and you should be all set.
