MS CRM 4.0 Setup error: ASP.NET is not installed

Today I got an error when installing MS CRM 4.0. Internet Information Services (IIS) => ASP.NET is not installed. (The screenshot is in Dutch but I tried the English installation too with the same results).

The log file didn’t helped much either

The report server was running on the same machine, I also created a test ASP.NET 2.0 website to test the IIS and this all worked without a problem. ASP.NET was installed and even had SP2. I tried to re-register ASP.NET by running the following command line.

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

Still the same result, so I googled this and I knew that I was in trouble when google didn’t give me any answers. At this point I knew that if I would ever find a solution I just need to blog this J

After some more searching and trying I decided to pull out the big guns and I started to use reflection on the setup dll’s to find out what exactly the setup was checking for.

I quickly found this function in the object Microsoft.Crm.Setup.Server.AspNetRegistrationValidator

protected override CheckResultInfo InternalCheck(IDictionary parameters)
{
bool flag = false;
try
{
using (DirectoryEntry entry = new
DirectoryEntry(“IIS://localhost/W3SVC/Filters”))
{
foreach (DirectoryEntry entry2 in entry.Children)
{
using (entry2)
{
if (entry2.Name.ToLower(CultureInfo.InvariantCulture).StartsWith(“asp.net_2″))
{
flag = true;
goto Label_00D1;
}
continue;
}
}
}
}
catch (COMException exception)
{
if (-2147463168 == exception.ErrorCode)
{
throw new InvalidOperationException(ServerResource.GetString(“IIS.Error.BadMetabasePath”, new object[0]));
}
if (-2147024891 == exception.ErrorCode)
{
throw new Exception(ServerResource.GetString(“IIS.Error.AccessDenied”, new object[0]));
}
throw;
}
Label_00D1:
if (!flag)
{
return new CheckResultInfo(CheckResult.Failure, base.GetResourceString(“AspNetRegisteredValidator.Failure.NotRegistered”, new object[0]));
}
return new CheckResultInfo(CheckResult.Success);
}

I used the code to create a console application and found that the only filter it could find was ASP.NET_4.0.30319.0. So the test failed because it was looking for asp.net_2.

The server was still an windows server 2003 and I found these filters by right clicking on websites => properties.

On the tab ISAPI Filters I found my problem. I added a new filter called ASP.NET_2.0.50727 and selected the following file c:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\aspnet_filter.dll

After doing this the CRM setup validated everything correct and the installation succeeded.
