Disabling Sophos Competitor Check on deploy (upgrade)

We are running Sophos alongside Cisco CSA. I have 450 machines that are unable to perform the upgrade unless I remove the Cisco CSA uninstall registry key, perform install, then re-import it. We will be running them together, and it's aggravating that Sophos doesn't want to play nice. They shouldn't be able to dictate whether I can run certain software on my machine, and if they do, it should default to playing nice with it rather than not installed. Now I have over 400 machines in an error state.

I have tried changing the ProductCatalog.xml and removing the entry for CSA in the CRT.config on the SUM install share. This does not work. The MSI fails with the same issue.

I have also tried adding the registry values:

SuppressCompetitorDetection=1

SuppressPreSAVCDT=1

...to HKLM\Software\Sophos\SAVService\SetupOptions\    as it says is possible here: http://www.sophos.com/support/knowledgebase/article/36207.html#MachGlobConfigFiles

Error logs continue to show that the MSI installation failed due to "A product with a similar function installed". 

Please help. Thanks

  • Thanks for the reply QC, I have tried both ways. I also did see that article. 

    Originally I tried the Auto-update way, relying on the subscription change to 9.7 Recommended. Like clock-work, the machines with CSA installed failed, while the machines without it installed perfectly.

    So I then tried deploying from the console while unchecking the 3rd party removal tool upon deployment with no luck. A different error resulted from the same reason (similar software found).

    I have since then attempted to use the registry settings on the host PC that I mentioned, but the auto-update and deploy from console still will not upgrade to 9.7.

    I also have sent an email to naconsulting@sophos.com regarding using an hour of consulting time for this issue, which may require a more in-depth look. I sent the email yesterday morning and have not heard anything back yet. In the meantime, I have over 400 endpoints not getting updates.
