Hello,
Thank you for your message.
Could you please double-check if you're trying to register your Viewer with a license key compatible with version 7 of Remote Utilities (i.e. the license key that is stored in the
*rlicense file extension)?
In case if you're trying to register your Viewer with a license key in a *txt format, please note that this license key is meant for version 6.10.10.0 and older of Remote Utilities and is not compatible with version 7 of the program. In this case please generate a new license key compatible with version 7 of Remote Utilities using
this form as the free license keys are not upgradable.
Hope that helps.
