When installing a Kaspersky application, you may receive the error message:
- “Digital Signature of installation files is missing”.
- “Error 1330. A file that is required cannot be installed because the cabinet file C:\ProgramData\Kaspersky Lab\KES.21.13\Setup\kes.cab has an invalid digital signature. This may indicate that the cabinet file is corrupt. Error 266 was returned by WinVerifyTrust.”
Solution
Follow the steps below to solve the issue.

If you are using Windows 7 or Windows Server 2008 R2, the error may occur if KB4490628 (update from 12 March 2019) and KB4474419 (update from 23 September 2019) are not installed.
In this case:
- Install Service Pack 1 (KB976932).
If this update is already installed, proceed to step 2.- Open Microsoft Update Catalog.

Step 4. Check if required root certificates are installed (for Windows users)
Administrator privileges are required to view certificates in the repository of the local computer.
For successful verification of the installation file signature on Windows, install the root certificates DigiCert Assured ID Root CA, DigiCert High Assurance EV Root CA, and GlobalSign Root R3:

+ R on the keyboard. - Type mmc in the Open field and click ОК.
- Select File → Add/Remove Snap-in.

- In the Certificates snap-in window, select Computer account and click Next.
- Select Local computer and click Finish.
- Click ОК.
- Expand the Certificates (Local Computer) node.
- Right-click Trusted Root Certificate Authorities and select All Tasks → Import.
- Click Next in the Certificate Import Wizard window.
- Click Browse, select the downloaded DigiCert Assured ID Root CA certificate and click Next.
- Select Place all certificates in the following store and make sure that the Trusted Root Certificate Authorities node is selected as the certificate store.
- Click Next.
- Click Next → OK.
- Repeat steps 10–15 for the DigiCert High Assurance EV Root CA and GlobalSign Root R3 certificates.
- Try installing a Kaspersky application once again.
Step 6. Remove malware from your computer
Use Kaspersky Virus Removal Tool.
For Windows XP and Vista, use the previous version of Kaspersky Virus Removal Tool.
Step 7. Check if there are any Kaspersky certificates in the Untrusted Certificates folder
Administrator privileges are required for viewing certificates in the repository of the local computer.
- Perform steps 2–8 from step 4.
- Expand the Certificates (Local Computer) node and select Untrusted Certificates.
- Make sure that there are no certificates (including DigiCert Assured ID Root CA, DigiCert High Assurance EV Root CA, and GlobalSign Root R3) in the Untrusted Certificates folder or one of its subfolders. If there are, delete them.
