Using VB 6 and Crystal Report 8.5
In client system while generating the report, I clicked export to PDF button in the report; it displayed Export, Export Option. Cho
In my case, on Windows 8.1 x64, the solution was to:
copy crtslv.dll and ExportModeller.dll from the dev machine to the C:\windows\SysWOW64\ folder
open a command prompt with administrator's privileges
That's all.
