When I open my installation, I get the following error.

I tried turning on the diagnostics, but no logs appear when I open the application. I can't seem to find any relevant information in the event viewer too.

Are there any other things I could try?

Hello Nathan,

You may find more suggestions in the KB article An Error Has Occurred While Loading the ReportDesigner's Workbench.

For example, there may be an invalid user.config file. You may try to delete or rename it, so the designer can recreate a valid one.

Hey Todor, 

Thanks for the reply.

I tried moving the user.config file, but on startup it doesn't recreate one. Is there a specific way I should be opening up the report designer to get crash logs?

Let me know if any more information would be helpful to solve this issue.
