1. My experience with TI 10 in the last weeks seems to be outstanding: Having upgraded last autumn the daily + weekly tasks work fine. Doing a new task rep. backup we found that this was not possible - TI 10 stops in the window where the partitions have to be displayed. Although the automatic task continue working without any problem. 2. After installing build 4871 everything works fine for about 10 days, than no backup could be done. Automatic tasks did there jobs well. Nevertheless backups could only be done using the rescue CD, but not within Windows. 3. I treated this problem in March and installed build 4942 - same problem, no backup ! 4. Then I tried a completely new installation after de-installation and got a strange fault just in the beginning of the install process "The installation was interrupted before Acronis True Image home could be installed. You need to restart the installer and try again." What does this mean ? 5. Doing several ways of possible solutions like - deleting temp folders etc - cleaning reg manually or by progs like jv16 (a lot of rubbish of Acronis an True Image !) - Windows Clean Up Utility - Acronis could not be found - contacting Acronis support without any answer Nothing works, at the moment TI 10 can not be installed, no backups, no tasks etc. Wht a backup software ! In this FORUM I found the link https://www.wilderssecurity.com/showthread.php?t=166837&highlight=Installer with the same problem with TI 9 - but no solution. Acronis support obviously found this fault interesting enough to answer after 10 days, but did not post a solution within this link. I would appreciate if someone has a solution or has some ideas. Thanks.
