Roxio installer wants to start

This is a problem with the Windows Installer. There is still an Installer configuration file on the machine that is starting the Installer when Legacy tries to open.

Please go to http://support2.microsoft.com/mats/Program_Install_and_Uninstall to run the "Fix-It" tool to fix the issue.

This is a famous issue with Roxio and all kinds of programs going back for years. If you go to the Roxio website you will see that their Roxio support guru says:

Your Windows Installer is running amok. It does this occasionally, and not just with Roxio programs.

Providing that you have an installation CD that you can reinstall Easy Media Creator with, I would suggest that you
-uninstall EMC if possible
-run the Windows Installer Cleanup Utility to straighten up the Windows Installer
-then reinstall EMC again.

The Installer Cleanup Utility is found at Microsoft's site here https://support.microsoft.com/en-us/mats/program_install_and_uninstall
You should read their instructions carefully and then use it to remove the entry which is causing the problem.
