How to get rid of legacy Acronis files

I am in a circle with old files creating problems.
Background. I have had many TrueImage versions, some trial other retail and it would seem its coming back to bite me.

I installed a retail version of TI Home 2010 (after a trial version) and was happy. I downloaded the .7046 version and my troubles began. I started (Bad move)the upgrade before uninstalling V.6053 and was told to uninstall the older version and reboot. I did this but when trying to install .7046 it halted said older version installed and uninstall. When I tried to install 6053 I was told a newer version was present and halted.
After many attempts I used my boot disk to go back to the OS state with .6053 however on reboot the blue screen of death cycled and choosing last good boot I had an OS but TI would not backup.

Is there some way I can clean my whole hard drive of TI files and registry entries so I can do clean install of TI home. I can't upgrade or go back.

Edit: I had a similar problem with Norton AV a few years back and they had an .exe file which cleaned out all the Norton registry and other files not uninstalled
