I am trying to install the ?15? day free trial. It was downloaded from the acronis web site. Seems to get part way through, then the bars that were counting up, start counting back (never seen that on an install before!) and I get a message saying the install was interrupted and to reinstall, which does exactly the same. XP, SP2. Switched virus protection off, made no difference. Have tried the standard and a custom install. Any ideas?
