While attempting to export the crystal report on a terminal server, it resulted in the following run-time error:
"No export DLLs found".
This errors message appears because the application cannot find the export DLLs on terminal server environment.
Solution
I copied all the below export related dlls (U2*.dll) that are in C:\Windows\CRYSTAL Folder to C:\Windows\System32 Folder. The problem is very well solved.
