I have no idea which Dinz instructions you were trying without a link to them but more information might help.
What is your operating system and service pack and how much free hard drive space and installed memory (RAM) do you have?
What security software do you now have installed or did you have installed before?
Thanks for your reply. My oprating system is Window 7 ultimate, SP1, 32-bit oparating system. Free space in C drive is 75GB and RAM is 3GB. Before trying to install McAfee antivirus plus, I had a trail version of McAfee total protection for 30 days. I did follow all the preinstallation steps as suggested in McAfee webpage. But still then I could not install McAfee antivirus plus yet.
kindly help please.
If you have any other anti-malware tools, especially Malwarebytes, please uninstall temporarily before trying this.
Try uninstalling whatever you have via Control Panel/Programs/Uninstall a Program then run the MCPR cleanup tool showing under Useful Links at the top of this page, reboot and then run the McPreinstall tool and reinstall from your online account.
If the problem persists then Technical Support should be able to help, it's a free phone call and also linked Under Useful Links.
