Tank you dear wilcroft,

I finally found the problem.there was a Charecter lcd in the QSYS and when I installed the Universities Program, It does not able to fit with program and default paths.these arror caused by libraries path.I add the library of Char lcd from " Propertice\libraries\" and manually add the char lcd file to project.the file are exsist in install directory of program \ IP \University Program\Video\Charecter LCD.after adding the files you can enjoy the design ;)
