Error installing CRM 4.0 in EDW "ASP.NET 2.0 is not installed"

 

When installing Microsoft Dynamics CRM 4.0 you may get an error in EDW stating "ASP.Net is not installed" - this can happen if you installed .Net Framework 4.0 on the machine. The CRM installation setup checks for settings within IIS and these settings are modified when you install Net 4.0 version on Windows 2003 servers.

The error you see within the EDW is the following:

error1

To resolve this please follow the below:

First step is to re-register ASP.NET via the command line:
C:\Windows\Microsoft.NET\Framework\v2.0.50727\aspnet_regiis.exe -i –enable

Secondly you need to bring back again this ISAPI filter in the IIS configuration.
- Log on the the Server and open IIS manager
- Expand Server Name | and then right click websites | Select Properties
- Click on the "ISAPI Filters" tab

ISAPI

- Click on Add button to add a new ISAPI filter for ASP.Net 2.0
   Name is as ASP.Net_2.0.50727
   Browse to the following file C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\aspnet_filter.dll
   Click ok - now the needed filter is back in the list.

Now click back on the CRM EDW window and Click next again to rerun the EDW check.
This should resolve the error.
