Regardless of the fact that this is an old version of RadControls for WinForms,
it should work without problems on Windows 7. I tested it on my Windows 7 PC and could not observe issues. However, please note that this version supports only Visual Studio 2008 and it has no integration with Visual Studio 2010 Toolbox. Still, it is possible to use our controls in Visual Studio 2010 by adding controls manually to the toolbox. Please consider the following steps:
Create a new project and open its Form
at design time.
Click the right mouse button on the Toolbox
Choose the Add tab
Right click with the mouse again and select the Choose items
Click the Browse
button at the right bottom corner of the dialog.
Navigate to the folder where you installed RadControls for WinForms
and select the bin folder.
Select the Telerik.WinControls.UI
Check one checkbox from the selected items and click OK.
Could you please confirm that this solves the issue? If not, describe your hardware and software configuration so we can investigate the case further. Thank you in advance.
I am looking forward to your reply.
