Hi ,
Yesterday I downloaded new version of avast Home edition . I didn`t have it before on my OS .
When I tried to install it , in second step of installation ,
setup window lost on screen !
When I tried for second time , this time
setup window lost when installation process had been started !
But after it when I click on avast setup icon , no installation window appears on screen so I can`t install it
I tried to install older version but again nothing loads for doing installation process .
What can I do ?
