I am getting the error code 2755 and reference 0xC0070643 when trying to install AVG 2012 on my Windows 7. I am worried that I have no antivirus software now. Can you help me with this please? Thanks.
Do you have any antivirus software installed on your computer? Such as McAfee, Norton or Trend. For your information, antivirus software will save a lot of registry files which can create problems when installing a new antivirus program. If this is the case, you need to uninstall your previous antivirus completely. Log on to your computer on Safe Mode and then right-click on the Start button and click the Open Windows Explorer. Search for the Program Files and then go to the AVG folder. Double-click on the AVG folder. Delete the AVG folder. You will be prompted that one of the AVG folder could not be deleted. It means there are still files left on your computer. To remove it, open your Task Manager and then select Processes. Look for the AVG process and then right-click it and click End Process. Go to the AVG folder again and delete it. Restart your computer and try to install AVG 2012 again.
