Problems while installing the WPF trial
I have downloaded the following file in order to install the WPF trial: RadControlsForWpfSetup_2011_3_1222.exe, but problems keep arising.
COMException was unhandled
Error HRESULT E_FA1, has been returned from a call to a COM component.
Check the ErrorCode property of the exception to determine the HRESULT returned by the COM object.
Get general help for this exception.
Here are some things I have done to try and solve it myself.
1) Rebooted and tried installing again.
2) Tried installing to different directories as administrator.
3) Temporarily disabled anti-virus and attempted install again.
4) Rebooted, disabled anti virus straight away and tried to install.
5) Used the debug option in the error window.
On my machine, I have telerik silverlight controls and .net 4.0. Do you have any further ideas that could be useful to me?
