Just created a chart for a customer and added it to the customized role center. The customer got a permission error when opening the client as there is no permission to read the table Chart no. 2000000078. Added read permission to that table to the user role and the client started. The next error was that the data visualization control was missing on the client machine.
A quick search pointed me to this download link. After installing and restarting the client everything is working as it should be.
