I had avg2011 (1120) installed and working fine on 3 xp sp3 systems. Attempting to install the latest update (1321) i consistently get the Error code 0xc0070643 with "Prepare driver installation failure) 0xE0010058 MSI action failed. I updated to the latest MSI from Microsft, unregistered and registered it and each of the 3 systems fails installation with the same error. On 1 system I wiped all evidence of AVG using the removal tool, manual file and directory deletion and a manual review of the registry. My logs are at https://rapidshare.com/files/457219301/avglogs04-13-2011.zip Same error in safe mode installation...Any thoughts appreciated
