I purchased & installed a boxed True Image 9.0. The CD says version DPV1.1. The Acronis site made me aware of an updated build, version 3677. I read in True Image quickstart guide that if an old version is already installed on your PC the new version would simply update it, there was no need to uninstall the older (they were referring to versions 8 & 9). So I installed 3677 "on top of" DPV1.1, afterall it was an update of the same version 9. Is this ok or should I remove my updated TI 9 & run registry mechanic & then install 3677? Next question: Am I to assume I'll need to create a rescue CD in either case? It was included on the boxed version CD--there was no need to create one. Thank you for your time.
