I SOLVED that
You may have similar issues when trying to install and run Pinacle TV Center Pro and installing Pinacle TV card drivers.
I have Windows Vista and it told me error "PMC Loader failed" when running Pinacle application and 2 times installation stuck at the 100% - "Finishing Installation..."
So i terminated Setup application using Ctrl + Alt + Del and restarted computer, then after restart i started setup from CD again and installed it again and everything went smooth. Setup after finishing asked for computer restart. So i restarted it and after restart it auto launched registration which i closed. Then it run Pinacle TV Center settup wizzard where i choosen my remote control type and searched for TV stations. All OK now.
So i advice this solution: restart and runing setup again or reinstalling after restart
