Apply schema error after Symantec Endpoint Protection plugin

I'm not sure what the preferred route for support of the SEP plugin is (it doesn't seem to be listed in the support options on the Symantec website), so I thought I'd start here!

I'm trialing an upgrade to Kaseya 6.3, and after installing the latest SEP plugin (2.1 RU1, having had to uninstall my old v1 in order for the 6.3 upgrade to proceed), I get an error at the 'apply schema' stage.  Uninstalling the plugin makes the error go away, re-installing it again brings it back.  Kaseya support suggest I speak to Symantec, so if there are any Symantec people listening, how might I make this error go away?

Thanks,

Sam
