On this page of the Acronis Knowledge Base, it states that "There is no need to uninstall the existing version of your copy of an Acronis product before updating it to the latest build". I have used TrueImage for several years, and that has always been true. Recently, I bought DiskDirector Suite 10 and, after installing it, Help > About indicated that it was build 1077. When I checked the Acronis update page, I found that the current build is 2160. After downloading it, I installed it over the existing installation, and was surprised to find that Help > About still reported build 1077. I installed 2160 again, with the same result. In the end, it was necessary to uninstall 1077, after which I was able to install 2160 successfully. Has this happened to other users? I would appreciate comments from the Acronis staff, as well.
