Just purchased Acronis True Image 11 Home edition. Was sent a download link. Running Windows Vista Premium Home edition on new Dell XPS 420 quad core processor. Have Windows Defender, Webroot Spysweeper with Anti Virus, Spybot Search and Destroy running. When I attempt to install after putting in the serial number the blue bar progresses and then retracts itself and indicates there is a problem with the installation and to attempt again. After several attempts, I finally went to Acronis website to register and it said it is a valid serial number but to contact support immediately. I haven't heard back from them. Could the reason they said to contact support immediately is that this is an illegal copy even though they said the serial number is valid? I went to Acronis website and did not see the vendor, Soft4Download as one that was selling illegal copies Does anyone have a clue as to what is occurring and how to get this to install?
