Error 2002 stands for "MD5 check failed" and it is received when the update files do not pass the MD5 checksum integrity check.
The downloaded files on the endpoint do not match the files present on the update server.
Troubleshooting Steps
The most common cause of this error is that the files are altered/corrupted during the download process by a third-party firewall present in the network, or by a content filtering application acting as a proxy.
Resolution
In this case, you need to whitelist the address to which the endpoint tries to connect to in your network firewall / content filtering application. Specifically, whitelist the internet update server address:
Upgrade.bitdefender.com:80
update.cloud.2d585.cdn.bitdefender.net:80
| Note:
To speed up troubleshooting, please also provide support tool logs from the affected workstation and associated relay/appliance. |
