Hi,

Our application recently moved to Win 7 64 Bit environment;  We are using telerik controls version 2011.2.712.35.
This error only occurs when there is an automation program recording the program. We are getting below exception causing application to crash. Any help with this error would be greatly appreciated.

Hello Piyush,

I answered your question in the support thread you started on the same topic. However, in case someone else encounters the same issue, please note that the exception is already fixed in our latest internal build. 

The fix will be officially out with the upcoming Q1 2013 release.
