Crystal Report Viewer freezes while setting report source (crystal runtimes 64bit only)

825 Views

Hi All,

within my C# application I am using the crystal reports viewer.

There is one report that isn't showing anything when loading to the viewer. The viewer element is loading, but I can only see the known grey background of the viewer.

It seems that the viewer freezes while setting the report source:

ReportViewer.ReportSource = repObj;

This only happens in a 64bit environment, whereas showing the report in a 32bit environment works without a problem.

I am using the current runtimes (version 13.0.20).

Is there someone who could give me a hint, what problem this may be?
