Using crystal shipped with VS2005 in VB6

Hello everyone,
I am stuck and would like to know if anyone can help me out.
In my (very) old VB6 application I am using data reports today.
I'll have to change to chrystal reports, because I am about to use unicode now.
I tried with the crystal 8 that we have licensed. But it doesn't work.
I thought of using the crystal that is shipped with our VS.NET2005 packages.
But I don't have any designer for this .NET crystal that can be used in VB6.
What could be the problem here?
Is this a misunderstanding from my side?

Thank you and greetings from Germany
Christian
