To resolve this issue, disable your anti-virus during the install/upgrade process.

  • TrendMicro
  • Sophos
  • Cylance Protect
  • Sentinel One (may cause resource exhaustions)

Anti-virus

McAfee Endpoint Security is known to inject outdated DLLs (version 14.00.X of vcruntime140.dll and mscvp140.dll) into the IIS process. This causes a “No products installed” error in the WS_FTP Server Manager and renders the client inoperable.

To resolve this issue, delete the problematic DLLs from the McAfee\Endpoint Security\Threat Prevention folder or uninstall McAfee Endpoint Security.

If removing the anti-virus is not possible, reach out to the McAfee support team to request a process to whitelist the IIS process or an updated McAfee version based on redistributable DLLs version 14.40 or later.
