Hello, Nosrat,      

Telerik UI for WinForms's R3 2019 SP is scheduled for this week. Feel free to download it once it is live and test again the Demo application where the fix is expected to be released.

Hello, Rajesh,    

We have improved the approach how the config file is searched and opened in the examples. You can download the Demo application from the following link: http://telerik-winforms-demos.s3.amazonaws.com/TelerikWinFormsExamplesLauncher.exe 

However, have in mind that it uses a different version than the official one. Hence, if you have another version in GAC, e.g. another installation, it would be necessary to uninstall it in order to test whether the downloaded Examples application would run properly after the introduced fix.

Could you please give it a try and see how it would work on your end? Thank you in advance for your cooperation.

I am looking forward to your reply.

Hello, Rajesh,    

The provided information is greatly appreciated. I have increased the priority of this case and we will do our best to improve the way this file is accessed. 

Currently, the possible solution that I can suggest you to launch the demo application is to open directly its Visual Studio solution. Open the installation folder (C:\Program Files (x86)\Progress\Telerik UI for WinForms R3 2019\Examples\QuickStart\), navigate to the solution (ExamplesCSVS2010) and start it. 

I hope this information helps. If you need any further assistance please don't hesitate to contact me.

Hello, Rajesh,    

Indeed, this behavior is not expected. However, we haven't had similar reports from other customers. I have logged it in our feedback portal by making this thread public. You can track its progress, subscribe for status changes and add your comments on the following link - feedback item.

 

I have also updated your Telerik points.

The provided screenshot is greatly appreciated. In order to further investigate why this error occurred on your end, we will need some more details. Does the specified folder exist "C:\Users\rpeddala\AppData\Roaming\Telerik\WinForms\Examples\Analytics\"? Is the config.xml really missing? Is it possible for you to not have permissions to open it? If the config.xml is there, would it be possible to share it with us? Thank you in advance for your cooperation.

I am looking forward to your reply.
