I suspect I have encountered another illegal reseller. I was looking for backup software at the local Staples. They had True Image 10 Home on their shelf. Based upon the information on the box, I made the purchase. When I went to install the software, I was asked for a serial number. None of the numbers I found on the box or CD was accepted. When I went to the Acronis site to find out where to find the serial number, I came across the Attention! Illegally sold Acronis software thread. Staples did not furnish a serial number when I made the purchase. I intend to return the software and get a refund, but before I do so, could you confirm that the list of authorized resellers is up to date? If Staples is an authorized reseller, but was inadvertently omitted from the list, then I will ask for a serial number rather than a refund. If Staples is not an authorized reseller, I will purchase True Image 11 Home directly from Acronis. A minor point: it would have been helpful if the User's Manual mentioned something about the serial number in the installation instructions.
