Fatal error in workbench. Now closing...
An error has occurred while loading the ReportDesigner's Workbench
Solution
The problem might come from a wrong configuration in the config file of the designer. To troubleshoot the described issue, attach a Trace Listener to the designer by adding the following to Telerik.ReportDesigner.exe.config
to generate a log file:
<system.diagnostics>
<trace autoflush="true" indentsize="4">
<listeners>
<add name="myListener" type="System.Diagnostics.TextWriterTraceListener" initializeData="c:\temp\StandaloneDesigner.LOG" />
<remove name="Default" />
</listeners>
</trace>
</system.diagnostics>
Inspect the generated file for any errors. You can also send us the log file in a support ticket with the configuration file of the designer.
Another possibility for the issue is to have an invalid user.config
file.
This is a file where the user preferences like connection strings, last opened files, window statuses, etc. are stored. This file can be found in the %localappdata%\Progress_Software_Corpora\
folder and there should be a subfolder called Telerik.ReportDesigner with a strong name key suffix. Inside, you should look for a folder named after the corresponding Reporting version. Here is a sample path:
Progress_Software_Corpora\Telerik.ReportDesigner.ex_StrongName_xvg2ahozm2u22wxtsw2egsvlddrzt5hj\18.2.24.924\user.config
For the older versions of Telerik Reporting the main folder may be
Telerik_AD
,Telerik
, orTelerik_EAD
.
Rename or move these files so the designer would start with the default values instead of reading them from these configuration files.
