When Acronis uninstalls you are usually asked if you want to keep the
product code number in case you wish to install acronis again at a later
date. Did you say No to this request? Also it sounds as if there are a few
registry entries relating to that version of Acronis still hanging around.
I'm not saying that this will work but you have nothing to loose.
Reinstall Acronis 9. Now visit this website
http://www.revouninstaller.com/revo_uninstaller_free_download.html and
download the free copy of revo uninstaller (it is completely free).
Install this and then run it. Once revo opens locate Acronis from the list
of programs visible in revo and uninstall it from within revo. Revo
uninstalls the main application and then searches for any files or
regisrty entries that Acronis has missed and allows you to delete them.
I've used Revo extensively and have found it to be very useful, especially
when an application refuses to uninstall all its files.
