Hi Janusz,
I guess you have english version installed. You can’t do a language-cross-install from self extract, unfortunately - because it needs all the packages you have currently installed - including english packages which are not included in setuppol.exe.
There are two ways:
-
uninstall english, reboot, install polish version
-
logon with admin rights, go to Control Panel, Add/Remove, Avast, push the button and select ‘update’. Reboot. Then do the same, select ‘Change’. Add polish. Now you can quit or you can go to program, select polish language as default and uninstall english from control panel.
