Hello,
I am attempting to install the WPF controls trial, and have downloaded the following file: RadControlsForWpfSetup_2011_3_1222.exe. I am having the same installation issue as this thread http://www.telerik.com/community/forums/aspnet-ajax/general-discussions/error-while-installing-new-version-for-telerik-ajax-asp-net.aspx
I have attempted the following to resolve the issue:
1) I have rebooted my machine and attempted to install a second time.
2) I located the installer directory in the %temp% folder, move this directory to a different location, and attempted to install it as an admin ( I am working in Windows 7)
3) I disabled my anti-virus program temporarily and attempted to install the trial.
4) Rebooted again, immediately disabled anti-virus and tried again.
5) Lastly I chose the debug option on the error window and launched VS2010. Attached is the error from Visual Studio.
I also have .NET 4 installed on this machine as well as the telerik silverlight controls, so I do not think the prerequisites are the issue. Do you have any additional ideas I could attempt to install the trial software?
Thanks,
Coulter
