Quest Chart View does not work. If you try to open the link http://server:port/_layouts/QuestSoftware/Telerik/Q22007SP1/NET2/RadControls/Chart/Image.aspx – it will result in the error message:

Title
INTERNAL – Quest Chart View Web Part Displays Broken ImageDescription
Cause
Previous version of Telerik controls (part of Quest Web Parts) was uninstalled incorrectly.
Resolution
Open appropriate web.config file and search for RadChart.Net2 - you will find something simillar:
<add assembly="RadChart.Net2, Version=3.1.0.0, Culture=neutral, PublicKeyToken=d14f3dcc8e3e8763" />
Backup this version of web.config file, delete the above raw and try to view the chart again - this should resolve the issue.
