When older versions of Sonic products (MyDVD, Roxio Creator, Sonic RecordNow!) are uninstalled, the Windows Uninstall application does not completely uninstall all Sonic components. Therefore, even though the Sonic program has been uninstalled, you are still prompted at startup to install the Sonic Activation Module.
Refer to Roxio Knowledge Base article, "Activate.MSI" message when launching MyDVD or Digital Media Studio
for information on downloading a tool to resolve this issue.
