1. At first you check your report Folder and all reports goes to the server. if don't go to the server please set report Build Action as Content

然后检查您引用的dll.并设置 所有 Crystal Decisions 参考 Copy Local True 都像

Then Check you you reference and dll. And set all Crystal Decisions reference Copy Local True like asenter image description here

然后检查您的计算机 Crystal Reports Service Pack (如果安装了Service Pack 22)，则必须在虚拟PC中安装 RUNTIME Service Pack 22 我希望一切正常，然后一切正常.
