I am using QTP 10 to automate an application using Syncfusion Grid

I have configured the Essential Test Studio dlls ( in swfconfig.xml with the right path.

But upon running a script using one of the methods in the dll, QTP throws an error.

"Could not load file or assembly 'Syncfusion.Grid.Windows, Version=7.303.0.20, Culture=neutral , Public token -..."

I have looked at the GAC, all the Syncfusion assemblies are of the ver 7.303.0.20

Can you please advise.

Updated the QTP ver to 11. QTP10 was a typo
