I downloaded and installed CR run-time file from here SAP Crystal Reports, developer version for Microsoft Visual Studio: Updates & Runtime Downloads
Also, I installed framework 4.5 into pc (win7) and web server (windows 2012)
I use vs2012 to develop a asp.net project with CR viewer.
The project works fine in pc.
But, once published to web server, CR viewer displays blank.
How to fix it?
