Right click on My Computer, Manage, Services, and check to see if the service mentioned is started. Here's the services display you should see. Note that the scheduler is the first one in the list.

 

Acronis True Image is a very robust program and works flawlessly unless one of the files is missing or a registry run command is missing for scheduler2 or True Image Monitor as shown in the attached screen shot.

Probably the simplest repair approach is to reinstall True Image.

 

Thanks to you both for the reponse. I am going to file the info for future reference should it be needed.
I had turned off the 'service' thinking that "scheduler" pertained only to automatic scheduling of backups, which I do not need. My short term memory is not too good, so I did not recall "messing" with Acronis only a short while ago.
