I had installed Acronis True Image 10.0.4942 and Disk Director 10.0.2161 on a Windows XP Home SP3 computer. For some reasons I wanted to split a data partition (NOT the system partition) into two separate partitions with DD. I wish I hadn't tried! The split itself worked fine. Unfortunately, TI and DD didn't work properly any more after the split. Both programs were "hanging" after they were started. OK, I checked all disks for errors with chkdsk myself. No problems were found. Finally I reformatted the empty partition with Windows. There are no problems whatsoever accessing data in those partitions with other Windows programs. However, Acronis products just didn't work any more. My next step was to deinstall TI and DD and reinstall again. I had some problems with deinstalling, and finally used the Acronis cleanup utility to remove all traces of Acronis products. Also used the MS Windows installer cleanup utility. Rebooted PC and started the install procedure. Well, first everything looks fine. Several files are copied to the proper folders, but just before the end the installation suddenly stops and hangs ("please wait..."). This is true for both TI and DD. I also tried some of the recommended tricks such as activating certain COM+ services or cleaning the TEMP folder, but to no avail. Now I have a fully functional system with no apparent traces of previous Acronis installations, but cannot install Acronis products any more. Weird. Does anybody have any ideas? Thanks.
