Error in starting Elements application

I'm using Windows XP in my computer. I recently installed some softwares in it which are; Elements 4.0 and premiere Elements 2.0. But after installing them, I am continuously getting really annoying error messages saying “application failed to start because pic eng dll is missing. Try reinstalling the application" and which really irritate me when I am using my computer.
Even I reinstalled the software several times but still I’m getting the same messages. I used recourses like Google to find out solutions, but I couldn’t get any solutions.
I would be very grateful, if you give me any nice suggestions on this regards.
Thanks.
