Answer 1

看错误是：The database DLL 'crdb_adoplus.dll' could not be loaded.

先检查一下 C:/Program Files/Common Files/Crystal Decisions/2.0/Bin （要是你改安装路径了就到对应目录下去找）下是否有 crdo_adoplus.dll 文件。如果没有就从 C:/Program Files/Common Files/Crystal Decisions/1.0/Bin 复制一份到该目录下。

还不行的话参考一下这个解决方案：http://www.c-sharpcorner.com/UploadFile/mahesh/crdb_adoplus08152006112827AM/crdb_adoplus.aspx

追问

电脑上没有这个目录
