Setup Process Error 1603 Kaspersky

When installing the Kaspersky Security Software on your computer, the setup error 1603 may occur, causing an installation failure.

Reasons:

  • The cause for the error is the security software that was used before installing the Kaspersky security tool. Because the log and cache files of the previously used security software interfere with the Kaspersky software files.
  • If you are installing a newer version of the Kaspersky software, but its older version is still present on the computer, the setup process gets interrupted.
  • Due to virus or malware on the computer, installing the Kaspersky may be prevented.
