When uninstalling via Windows standard tools some files and folders of the previously installed antivirus programs may still reside in the system; that is why you are recommended to check the Program Files folder. If the Program Files folder contains any subfolders or files of the antivirus programs installed earlier, you are recommended to remove them. Then, try to install a Kaspersky Lab product once again.
Be careful, the content of any folder you choose will be deleted!
If all remains of your previous anti-virus software were removed, or you have not had any anti-virus software installed on your computer, but you cannot install a Kaspersky Lab product, then create a request to Kaspersky Lab Technical Support via the My Kaspersky Account service. Attach to your request a report of the Getsysteminfo tool. In the request, give detailed description of the problem and the actions necessary to reproduce the problem.
See how to manage My Kaspersky Account service in FAQ for My Account.
