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

  • The registry keys are obviously not working. Do the clients require a reboot before those reg keys will work?

    This is a log from the CustomActions Log for the latest install attempt. Doesn't look suppressed...
