Can anybody please tell me where I can get crystalEnterprise.dll

Hi,

I am working on Business Objects .net SDK version xiR3 . I installed .net sdk but I could get dlls like businessobjects.dsws or crystaldecision.desktop.

But when I gone through sample code they use crystalenterprise or com.crystaldecision name spaces.

Where Can I find these dlls? What I am doing wrong.

Even I tried installing xiR3 sp2 fixpack 2.7

Thanks in advance,

Rajendra
