How to confirm that setup was successful

The following files are copied to the %WINDIR%\Microsoft.NET\Framework\v1.0.3705\ folder:

   Version       File Name
   -------------------------------
   1.0.3705.272  Aspnet_isapi.dll
   1.0.3705.272  Aspnet_wp.exe
   1.0.3705.272  Aspnet_regiis.exe
       --        Aspnet_perf.ini
       --        Aspnet_perf2.ini
   1.0.3705.272  System.Web.dll

The following files are copied to the %WINDIR%\Microsoft.NET\Framework\v1.0.3705\ASP.NETClientFiles\ folder:

   Version  File Name

Additionally, System.Web.dll is installed to the global assembly cache (GAC). If files are locked during installation, the updated version of System.Web.dll does not install to the global assembly cache.

To check the version of the assembly in the global assembly cache, follow these steps:

In Microsoft Windows Explorer, open the %WINDIR%\assembly folder.
Right-click System.Web, and then click Properties.
In the System.Web Properties dialog box, click the Version tab. The version information appears in the File Version box.

If the installation succeeded, the version of System.Web.dll is 1.0.3705.272. If the version is not 1.0.3705.272, the installation did not succeed. For more information about how to repair the installation, see the How to recover from a failed installation section of this article.

How to recover from a failed installation

If Setup was unsuccessful, ASP.NET pages will not run, and an error page will be returned. The error page may indicate that the server cannot be found and that a DNS error may have occurred. When you try to debug a project in Visual Studio .NET, you may receive the following error message:

Error while trying to run project: Unable to start debugging on the web server. Would you like to disable future attempts to debug ASP.NET pages for this project?

To recover from a failed installation, follow these steps:

Restart the computer to make sure that all files are unlocked.
Use the Add or Remove Programs tool in Control Panel to remove "Microsoft .NET Framework Hotfix Q322289 (English)," and then restart your computer.
