Long time user of ATI 2009, I decided to check out the trial version of ATI 2012 despite the reported problems.
Tried to install it twice after uninstalling ATI 2009, first with Revo, then with the ATI cleanup. Both times it hung during installation (seemed to be near the end). After stopping the process, and trying to deinstall it to start again, the PC hung on shutdown and subsequently on reboot. Had to restore using an ATI 2009 backup on both occasions.
Tried in on another PC and it installed OK. However the email notification is broken (as reported in other threads), and Acronis don't seem to be doing anything about it. Also, I couldn't find any way to set the "From" email address.
Finally, the backup that I kicked off on the 2nd PC failed during verification.
Can't be bothered to waste any more time on this product. Don't think I'll be buying it any time soon.
