I would suggest that you check Control Panel/Programs to assure that Premiere Elements 11 is not installed on your Windows 8 (assumed 64 bit).
Then do a run through with the free ccleaner (regular cleaner and registry cleaner parts). Then do the reinstall with antivirus and firewall(s) disabled.
What were the original problems that caused you to uninstall Premiere Elements 11?
We will be watching for your progress.
Thanks.
