Comodo firewall no longer works after upgrade

Hello,
i recently upgraded to Windows 7 from Vista.
unfortuantely now my comodo firewall now keeps giving the error messege:
the procedure entry point _createFrameWork@0 could not be located in the dynamic link library framework.dll.

Ive tried uninstalling via windows own uninstall and found i cannot uninstall. Then i tried redownloading new Comodo firewall and keep getting same error messge.
