Is there any way to check Symantec Corporate Edition to see the subversion beyond 10.1 ? The registry key mentioned here only displays 10.1

If you've seen some of the recent activity around 10.1 you'd know that certain versions prior to 10.1.4.4000 (?) had a vulnerability that modern viruses could attack. For that reason I would like to deploy newer versions based on the current full version string. Any ideas?
