出现Graphics not initialized (use “initgraph”)

下面的程序在执行过程中出现Graphics not initialized (use “initgraph”)
#include <graphics.h>
      int main()
      {
           int gdriver, gmode;
           gdriver=VGA;
           gmode=VGAHI;
           initgraph(&gdriver, &gmode, "c:\\tc");
           bar3d(100, 100, 300, 250, 50, 1);   
           getch();
           closegraph();
           return 0;
      }
在turboc2中没有出现,查资料说是egavga.bgi文件所在的目录的路径不对,但更改路径还是不行,请各位朋友帮帮忙.谢谢!~~~

#include <graphics.h>
      int main()
      {
           int gdriver, gmode;
           gdriver=VGA;
           gmode=VGAHI;
           initgraph(&gdriver, &gmode, "C:\\Win-TC\\projects");
           bar3d(100, 100, 300, 250, 50, 1);   
           getch();
           closegraph();
           return 0;
