1) 菜单栏“TOOLS（工具）”—>“Option（选择）” —>“Directories（目录）”
如果你是按照初始路径安装vc6.0的，（如果你装在其他盘里，则仿照其路径变通就行(我就是装在D盘)）。 路径应为： show directories for更改为:executatble files: C:/Program Files/Microsoft Visual Studio/Common/MSDev98/Bin C:/Program Files/Microsoft Visual Studio/VC98/BIN C:/Program Files/Microsoft Visual Studio/Common/TOOLS C:/Program Files/Microsoft Visual Studio/Common/TOOLS/WINNT
show directories for更改为:include files: C:/Program Files/Microsoft Visual Studio/VC98/INCLUDE C:/Program Files/Microsoft Visual Studio/VC98/MFC/INCLUDE C:/Program Files/Microsoft Visual Studio/VC98/ATL/INCLUDE
show directories for更改为:library files: C:/Program Files/Microsoft Visual Studio/VC98/LIB C:/Program Files/Microsoft Visual Studio/VC98/MFC/LIB
show directories for更改为:source files: C:/Program Files/Microsoft Visual Studio/VC98/MFC/SRC C:/Program Files/Microsoft Visual Studio/VC98/MFC/INCLUDE C:/Program Files/Microsoft Visual Studio/VC98/ATL/INCLUDE C:/Program Files/Microsoft Visual Studio/VC98/CRT/SRC （若无，暂时可不选）
如若还不成功，参照本人博客另一博文将注册表键值删去即可，再打开看
我也花了很长时间才解决的，一点儿经验，晒给大家
