open 'Warcraft III' folder & add 'Run as Administrator' under 'Compatibility' tab to every EXE file but 'BlizzardPrepatch.exe' which shows no 'Compatibility' tab run './War3-1.27-Installer-deDE-TFT/Installer.exe' as administrator & exit setup when finished
In fact i like kaspersky, but over the last years they added much too much options, so you can never be sure whether it is kaspersky blocking anything and from my experience, most time it really is kaspersky doing something annoying.- run './War3-1.27-Installer-deDE-ROC/Installer.exe' as administrator & exit setup when finished
