You have to reboot your computer before running Acronis True Image

HI, I’ve installed the Acronis True Image WD version to migrate an existing D drive to a new WD SSD. I installed the AcronisTrueImageWD_28080 version and when I run it, I get the following message “You have to reboot your computer before running Acronis True Image”. I’ve had this happen on 2 computers. A laptop and another PC didn’t have any issues and cloned the drives with no problems. I don’t know what to check. There seems to be very little out there on this problem. Any suggestions? Thanks.

Rebooting left me with same issue. I have the SSD connected via USB. No instructions on best practices.
