This article discusses how to switch between the 32-bit version of Microsoft ASP.NET 1.1 and both the 32-bit version and the 64-bit version of ASP.NET 2.0 on a 64-bit version of Microsoft Windows.
When you install both versions of ASP.NET, you may receive error messages if you do not perform steps to enable each ASP.NET environment to run in Microsoft Internet Information Services (IIS) 6.0. For example, when ASP.NET is not set up correctly, you may receive the following error message from a Web page:
Error messages that are similar to the following may be logged in the Application log.

IIS 6.0 supports both the 32-bit mode and the 64-bit mode. However IIS 6.0 does not support running both modes at the same time on a 64-bit version of Windows. ASP.NET 1.1 runs only in 32-bit mode. ASP.NET 2.0 runs in 32-bit mode or in 64-bit mode. Therefore, if you want to run ASP.NET 1.1 and ASP.NET 2.0 at the same time, you must run IIS in 32-bit mode.
Note If you have Microsoft Exchange Server 2007 installed on the computer, use the instructions for ASP.NET 2.0, 64-bit version.
Before you can switch between the different versions of ASP.NET, visit the following Microsoft Developer Network (MSDN) Web site to download and install both the .NET Framework 1.1 and the .NET Framework 2.0:

Technical support for x64-based versions of Microsoft WindowsIf your hardware came with a Microsoft Windows x64 edition already installed, your hardware manufacturer provides technical support and assistance for the Windows x64 edition. In this case, your hardware manufacturer provides support because a Windows x64 edition was included with your hardware. Your hardware manufacturer might have customized the Windows x64 edition installation by using unique components. Unique components might include specific device drivers or might include optional settings to maximize the performance of the hardware. Microsoft will provide reasonable-effort assistance if you need technical help with a Windows x64 edition. However, you might have to contact your manufacturer directly. Your manufacturer is best qualified to support the software that your manufacturer installed on the hardware. If you purchased a Windows x64 edition such as a Microsoft Windows Server 2003 x64 edition separately, contact Microsoft for technical support.
