It appears that you already have ESET Internet Security installed (v11) and attempting to install an old ESET Smart Security (v9) over it. If there's a problem with EIS, uninstall it and install it from scratch. Do not install an old ESS v9.

sir, i want to install eset smart security 9 v. pls tell me how to uninstall eset internet security version. pls help to resolve this issue.

Why do you want to install v9 which contains less protection features and bugs that were addressed in newer versions? Also v9 will reach it's end-of-life in 2019 and users will be upgraded to the latest version except those using Windows XP.
