Hi,
I believe there might be some restrictions in registry due to which you are not able to install AVG.
1) Remove traces of AVG. Go to this link, download and run the tool to remove AVG
http://www.avg.com/ww-en/download-tools2) Then restart the computer.
The following methods will reset registry permission.
1) Go to this link, download and run subinacle
http://www.microsoft.com/downloads/details...;displaylang=en2) Copy the below commands and paste it in a notepad
__________________________________________________
cd %systemdrive%\
cls
@echo off
echo You are about to reset your security settings to default using SUBINACL
pause
echo Please wait while default security settings are applied
cd "%ProgramFiles%\Windows Resource Kits\Tools"
subinacl /subkeyreg HKEY_LOCAL_MACHINE /grant=administrators=f
subinacl /subkeyreg HKEY_CURRENT_USER /grant=administrators=f
subinacl /subkeyreg HKEY_CLASSES_ROOT /grant=administrators=f
subinacl /subdirectories %SystemDrive% /grant=administrators=f
subinacl /subkeyreg HKEY_LOCAL_MACHINE /grant=system=f
subinacl /subkeyreg HKEY_CURRENT_USER /grant=system=f
subinacl /subkeyreg HKEY_CLASSES_ROOT /grant=system=f
subinacl /subdirectories %SystemDrive% /grant=system=f__________________________________________________________
3) Name this file as "reset.bat" and save it on desktop.
4) Double click on reset.bat from desktop to reset registry.
5) Then try to install AVG, it should work.
