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.
