I downloaded and installed TI 11.8101 over 8053 in Windows XP SP2 without any problems. Since the name changed for the Safe mode add-in, I downloaded that also and installed it. It actually asked if I wanted to Modify, Repair or Remove Safe mode, so I picked Repair and it reinstalled. This probably isn't necessary. In Windows the new build shows as 8101 in Help / About. I created a new Rescue CD, and it show 8054 in Help / About. Oops, another little detail missed by Acronis programmers. Oh well, it's not the old 8053 number. The list of changes posted on the Acronis web site was not at all encouraging for this build to actually have fixed the many propblems reported for TI 11.8053. Who has found out anything?
