I had an occasion to help a friend upgrade build 9709 to 9796. This wasn't working well for him and he was ready to give up (really frustrated having spent many days without success). I suspected that he had improperly entered the serial number(s). I had asked him to e-mail a text file showing the serial numbers which he ignored. In his attempts that failed he got an upgraded serial number and that didn't work either. Being totally frustrated he sent me a screen shot showing the page where you enter the two serial numbers (he had an upgrade). When I saw the screen shot file I immediately saw the problem. He had correctly entered his latest serial#. On the second line he entered the older serial# also for True Image 2009 taking a literal interpretation of the instructions where it reads "Please enter the serial number for the current version." I find this misleading also but I knew what the intent was. For a new user this could be a problem. Additionally the reference to enter the 64 character (probably 71 would be more correct) serial# can be confusing when entering a prior version that requires fewer characters. I realize that there are many ways to express this and it simply was my thought at the time. To follow is an image that hopefully will illustrate the matter.
