Unable to Install Sophos EDR, requestion full version

I am trying to install Sophos in some remote sites which is protected by Sophos XG. While it is working on some sites, I am unable to install on most of the sites.

I already added the following to allow FW rule but it seems it doesnt connect to Sophos Central on those sites.


I tried SophosInstall.exe with command and even with the message relay server. The Device register but most of the components don't install and always show red.

SophosSetup.exe --quiet --messagerelays=[IP address]:8190

The recommendation as always to install and use SophosSetup.exe which is not working and it is not what I want

I created a rule and added the following to the allowed list:




But even with this, it doesnt work sometimes as per logs:

  • Hi  

    I have moved this thread to the Sophos Central group from the Support Portal group. This usually generally indicates that there is Pending File Rename Operation flagged in the registry. The PendingFileRenameOperations registry value indicates that a user or program has tried to rename a file that is in use. The file names are stored in the value of this entry until the system is restarted and then they are renamed. 

    Please perform the following steps after taking a full backup of your Windows registry. Please note that if you face any difficulties in performing these steps, then please open a support ticket with us - support.sophos.com

    1.  Open the Windows Registry Editor: Please ensure you make a full backup before making any changes to the registry

    2.  Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager.
    3.  Right-click the PendingFileRenameOperations value and select Delete from
    the context menu. When prompted, click Yes to confirm the delete operation.

    4. Close Registry Editor

    5. Restart your computer and attempt to run the installation again.

  • Thanks for the advise.

    I managed to find the root cause but is it possible to provide standalone installation that will only require to register to central instead of the current standalone which doesnt have most of the recent component updates and require to download them online?

  • Hi  

    That's great! Can you please let us know how did you manage to resolve it? 

    At the moment that is not possible. You can try setting up an update cache so that your bandwidth is saved and the required files are downloaded from your local update cache server. For more info, please see: https://support.sophos.com/support/s/article/KB-000035498?language=en_US&c__displayLanguage=en_US

  • Enabling the web cache on Sophos XG and installing from Relay server doesnt work for first-time installation. It seems some of the components are still required to be download directly from Sophos Central

  • Yes, the Central Install has to reach out to our Servers at least once. You can do that on one endpoint that copy the AutoUpdate folder and use that as a local install source for future installs. However, the AutoUpdate function will keep reaching out to get updates from us - so if the initial install is failing then there is concerns future updates will as well. 

    It is better to setup and Update Cache in the local network that 100% has the correct access out.


    From there, the other endpoints can update from it later.

  • It is not a perfect solution as it still fail sometimes. I created a firewall rule for the PC I want to install Sophos EDR on and passed all traffic without any control. Then I disabled the role once the installation is completed.

    I tried to copy the Install Cache from Program Data but it didn't work as it downloaded all items again. Sometime, I do reinstallation 3-4 times before it work and I can see it download all cache almost everytime. My problem is that everytime it download around 1GB which explains why it fail on the remote site which has VSAT
