What are the most common causes of a fatal error while installing Kaspersky?

The most common causes of this error are:

• C:Junction ProgramData's point may be pointing to the wrong spot.
• A Leftover Registry Key may be present on your device.
• There may be leftovers from a previous protection kit that hasn't been fully removed.
• This error can also be caused by a device cache file.
• Another security device on your machine may be the source of the problem.

reason

The Kaspersky Endpoint Security installer uses the Open Local Machine GPO (GPO OPEN LOAD REGISTRY) feature to create a local group policy that enables you to disable Windows Defender and configure the installation settings. The error occurs if the domain policy prevents disabling Windows Defender on a target host.

 response

• On the target host, apply the GPO (Group Policy Object) policy with default settings — Default Domain Policy, where all Windows Defender values are set to Not configured.
• On target hosts, force the community policies to be applied.
• Restart the machine if necessary.
• Reinstall the application if necessary.

What do you do if the solution doesn't work?

If the above solution did not work, try the following:

• Remove the host from the Active Directory domain for the time being.
• Local community rules should be reset.
• Reinstall the application if necessary.
• Return the host to the Active Directory domain after the installation is complete.
