KDZ Troubleshooting

Frequent KDZ Opening Issues

Kaspersky Anti-Virus Isn't There

When trying to open your KDZ file, you get the error "Can't Open KDZ File Type". Customarily, this means that Kaspersky Anti-Virus is not installed on %%os%%. Your operating system cannot associate your KDZ with Kaspersky Anti-Virus, so double-clicking the file won't work.

Tip: If you have another software that you know opens KDZ files, you can select it by hitting the "Show Apps" button.

Incorrect Kaspersky Anti-Virus Version

It is possible that your version of Kaspersky Anti-Virus isn't able to open your Kaspersky Virus Bases File file due to incompatibility. Visit the Kaspersky Lab website to download (or purchase) the latest version of Kaspersky Anti-Virus. This issue mainly occurs when your Kaspersky Virus Bases File file was created by a newer version of Kaspersky Anti-Virus than you have on your PC.

Tip: You can sometimes get hints about the right program version by right-clicking on the KDZ file, selecting "Properties", and looking at the version information.

Summary: In either case, the majority of problems opening KDZ files are related to not having the correct software application installed on your computer.
