Troubleshoot KDC Files

Common KDC Opening Problems

Kaspersky Anti-Virus Isn't There

When trying to open your KDC file, you get the error "Can't Open KDC File Type". If this is the case, it's usually due to the fact that you do not have Kaspersky Anti-Virus for %%os%% installed on your computer. You won't be able to double-click to open your KDC because your OS doesn't know what to do with it.

Tip: When another KDC application is installed, you can choose to open it by selecting "Show Apps" and using that program.

Kaspersky Anti-Virus Requires Update

It is possible that your version of Kaspersky Anti-Virus isn't able to open your Kaspersky Virus Database File file due to incompatibility. Visit the Kaspersky Lab website to download (or purchase) the latest version of Kaspersky Anti-Virus. This problem is most common when you have an older version of the software application, and your file was created by a newer version that it cannot recognize.

Tip: Investigate your KDC file by right-clicking and selecting "Properties" to find clues on what version you need.

Conclusion: The majority of KDC file opening issues are due to not having the correct Kaspersky Anti-Virus version installed.

Additional KDC Opening Issues

Errors opening Kaspersky Virus Database File files can still occur even with the latest Kaspersky Anti-Virus software installed on your computer. Other KDC opening errors can be created by other system problems inside of %%os%%. Other contributing causes:

• KDC file type Registry entries are wrong
• Corruption of the KDC file description inside the Registry
• Partial installation of Kaspersky Anti-Virus that did not fully complete
• Your KDC file is corrupted (issues with your Kaspersky Virus Database File file itself)
• KDC file integrity has been compromised by malware
• Hardware related to KDCs has device driver corruption
• Your computer does not have the adequate system resources to open the Kaspersky Virus Database File format
