I solved my problem.

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
Then Check you you reference and dll. And set all Crystal Decisions reference Copy Local True like asenter image description here
Then check you Computer Crystal Reports Service Pack if you install Service Pack 22 then in your virtual pc must be install RUNTIME Service Pack 22 I hope if every thing is ok then it work properly.
