Sometimes after activating MetaDefender Core v4, during the engines downloading, some of the engines may be in "failed" or "permanently failed" status.

In this case, you can do the following :

• Make sure your system adheres to our system requirements.

• Go to Inventory → Nodes page and check the Nodes one by one and see if there is any issue displayed on the Issues tab. Resolve the issues displayed. Example of issues:

  • If Data Sanitization is the single engine which is not active, you may have to install .NET framework 4.6 and restart the MetaDefender core services.

  • If you have a local antivirus product installed, you have to add both the OPSWAT and the resources folders to the exclusions list of that antivirus product and then follow the above steps again.

• Disable and enable each failed engine, one after another on the Inventory → Technologies page.

If you have followed all of these steps and your engines are still unusable, please see how to create support package, login into OPSWAT Portal and open a ticket with us with the support package attached.
