    This patch along with previously released path 2179 fails to install on servers running OS prior to Server 2012, so looks like Trend have removed support for SBS 2011

      I got the feedback from a German reader, that the patch failed on several Windows Server 2008 and 2012 R2.

      FYI, got the patch to work on SBS2011 server – after initially failing. Check c:\TMPatch.log and it will tell you what it’s failing on. On the server I was doing, it couldn’t copy isapiclient.dll (even after stopping the service). Stopped the service manually, renamed the dll, cleaned out c:\Windows\temp and tried again – worked.

      I was having same issue on 2012 R2. In the properties of folder ‘C:\Program Files (x86)\Trend Micro’ added logged in user under security tab with full access.
      Ran update and installed with no issues

    Hi Damian, have same issue on SBS2011 servers.
    Have you seen any post-installation problems?

    Thank you Damian D-M!
    I had the same problem on a SBS2011 and I could solve it with your advice.

    Hi, is anyone else seeing Win10 clients popping up with ‘your computer is not protected – firewall is disabled etc’ notification? Clients also spammed with notifications saying they are receiving an update. They also seem to be showing as offline randomly in the admin portal even though the client is showing as connected.

  6. Alessandro says:

    Hello Matthew.

    My problem after patch 2185: the agents on the clients are unable to update to the latest pattern if they remain offline for more than 3 days.

    After 3 days offline, the only way is to manually copy the latest pattern file in the Security Agent folder.
    After this manual update, the agents start again to automatically update itself.


    • Matthew Warburton says:

      Thanks Alessandro. It seemed in my case there was an issue with the latest patch on the server and all the clients were stuck in an update loop – putting stress on both clients and the Trend server. I had to do a full re-install of the Trend server for the clients to update.

      Delete the pattern files should solve the issue – a blog post will follow.

    Different situation on two SBS 2011 servers:
    Both needed the isapiclient.dll to be renamed before Patch 2185 could be installed successfully.

    Both updated their agents to version 2041, but only one of the servers also applied patch 2185 to the agents. The second one does not apply the hotfix.
