Analysis Center 2.7 installation fails on 64-bit server with ASP.net error "unable to retrieve version information"
AC 2.7 Preinstall shows passed but the last check shows ASP.net framework "unable to retrieve version information"

ASP.NET can be re-registered with IIS. The specific method depends on the operating system being used.

Windows 2000/XP

To fix this on Windows 2000 or Windows XP, run this command from the Start>Run box or a command prompt (assuming the system directory is C:\Windows):

.Net 1.1: C:\Windows\Microsoft.NET\Framework\v1.1.4322\aspnet_regiis.exe -i

.Net 2.0: C:\Windows\Microsoft.NET\Framework\v2.0.50727\aspnet_regiis.exe -i

Windows 2003

On Windows 2003, ASP.NET must be both installed and enabled.  To install ASP.NET:

1. On the taskbar, click the Start button, point to Control Panel, and then click Add or Remove Programs.
2. In the Add or Remove Programs dialog box, click Add/Remove Windows Components.
3. In the Components box in the Windows Components Wizard, click the Web Application Server check box, and then click Next.
4. When the Windows Components Wizard has finished configuring Windows Server 2003, click Finish.

To enable ASP.NET, run this command from the Start>Run box or a command prompt (assuming the system directory is C:\Windows):

.Net 1.1: C:\Windows\Microsoft.NET\Framework\v1.1.4322\aspnet_regiis.exe -i -enable

.Net 2.0: C:\Windows\Microsoft.NET\Framework\v2.0.50727\aspnet_regiis.exe -i -enable

.Net 2.0 (64-bit): C:\Windows\Microsoft.NET\Framework64\v2.0.50727\aspnet_regiis.exe -i -enable

ASP.net needs to be re-registered.
