I’m trying to install the trial for the RadControls for ASP.NET AJAX. I have Visual Studio Express 2012 for Web (with Update 3) installed on Windows 8 Pro x64. According to the system requirements, this is supported. Its the Q2 2013 version, and I've tried both the .exe and the .msi. However, the installers will not let me select VS2012 stating it must be installed. It shows and pre-selects VS2010 as an option even though I do not have this installed. Any ideas what I can do to install this trial?
