[Can not Install Symantec Corporate Edition 10 after uninstalling versi]

I have already tried uninstalling version 9 first, but with the same results. And I have about 200 Clients to upgrade, and would rather not have to reinstall Windows on all of them.

[Can not Install Symantec Corporate Edition 10 after uninstalling versi]

I am in the process of upgrading Symantec Antivirus Corporate Edition v 9 Clients to Version 10. This requires version 9 to be uninstalled, and then 10 Installed.

In a few instances the install will just freeze part way in its process and will stay there indefinitely. Restarting the computer, trying to reinstall it again results in the same issue. Even trying to install version 9 again also fails in the same manner.

Has anyone else encountered this issue, and is so, how did you get around it.
