I using visual studio 2010 to development asp.net application using .net framework 3.5 and i'm using crysatl report for VS 2010. I deployment my application on server that contain .net framework 3.5 and crystal report 2008 runtime package. But i have some error. I see that the runtime backup for crystal report 2010 is required .net 4. and i can't setup .net 4 in my server.
What is the steps should i do?
