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
| 09:28:53|Verbose| Method entry: Microsoft.Crm.Tools.EDW.Framework.EDWTool.RunSnifferValidate Internet Information Services (IIS) 09:28:53|Verbose| Calling BaseGroup.Validate 09:28:53| Info| Check IIsInstalledValidator: Success 09:28:53| Info| Check IisAdminServiceValidator: Success 09:28:53| Error| Check AspNetRegisteredValidator : Failure: ASP.NET 2.0 is niet geïnstalleerd. 09:28:53| Info| Check W3svcServiceValidator: Success 09:28:53| Info| Check IsIIs5IsolationModeValidator: Success 09:28:53|Verbose| BaseGroup.Validate completed 09:28:53|Verbose| Method exit: Microsoft.Crm.Tools.EDW.Framework.EDWTool.RunSnifferValidate |
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.
