Microsoft Windows Pro x64 Personal Experiences

I finally broke down and purchased an AMD Turion64 laptop which came with the 32bit version of Windows Home SP2, which was totally unacceptable. Why have a 64bit system only to run a 32bit operating system? In my mind there was none so the first thing I did was format the drive and install Windows Pro x64.

I soon realized that finding 64bit drivers was not as easy as I hoped. After hours of searching Google I finally located drivers for the video card and sound card. The only remaing device that I could not locate a driver for was the modem and since I do not use dial up I decided to give up on the ide of locating a driver for the modem. At this point life is great!

My next step was to install Visual Studio .NET 2003 and 2005 since I do development both in 1.1 and 2.0. This in itself did not present any problems rather the first issue I ran into was when I tried to execute an application developed in .NET v1.1. The browser returned an error stating "Service Unavailable". Ahhh, it is always something with me. I found the answer at Microsoft.

In short here is the answer:

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

After you install the redistributable packages, you can switch between the different versions of ASP.NET. To do this, follow these steps for each ASP.NET version:

ASP.NET 1.1, 32-bit version
To run the 32-bit version of ASP.NET 1.1, follow these steps:

  1. Click Start, click Run, type cmd, and then click OK.
  2. Type the following command to enable the 32-bit mode:
    cscript %SYSTEMDRIVE%\inetpub\adminscripts\adsutil.vbs SET W3SVC/AppPools/Enable32bitAppOnWin64 1
  3. Type the following command to install the version of ASP.NET 1.1 and to install the script maps at the IIS root and under:
    %SYSTEMROOT%\Microsoft.NET\Framework\v1.1.4322\aspnet_regiis.exe -i
  4. Make sure that the status of ASP.NET version 1.1.4322 is set to Allowed in the Web service extension list in Internet Information Services Manager.

ASP.NET 2.0, 32-bit version
To run the 32-bit version of ASP.NET 2.0, follow these steps:

  1. Click Start, click Run, type cmd, and then click OK.
  2. Type the following command to enable the 32-bit mode:
    cscript %SYSTEMDRIVE%\inetpub\adminscripts\adsutil.vbs SET W3SVC/AppPools/Enable32bitAppOnWin64 1
  3. Type the following command to install the version of ASP.NET 2.0 (32-bit) and to install the script maps at the IIS root and under:
    %SYSTEMROOT%\Microsoft.NET\Framework\v2.0.50727\aspnet_regiis.exe -i
  4. Make sure that the status of ASP.NET version 2.0.50727 (32-bit) is set to Allowed in the Web service extension list in Internet Information Services Manager.

ASP.NET 2.0, 64-bit version
To run the 64-bit version of ASP.NET 2.0, follow these steps:

  1. Click Start, click Run, type cmd, and then click OK.
  2. Type the following command to disable the 32-bit mode:
    cscript %SYSTEMDRIVE%\inetpub\adminscripts\adsutil.vbs SET W3SVC/AppPools/Enable32bitAppOnWin64 0
  3. Type the following command to install the version of ASP.NET 2.0 and to install the script maps at the IIS root and under:
    %SYSTEMROOT%\Microsoft.NET\Framework64\v2.0.50727\aspnet_regiis.exe -i
  4. Make sure that the status of ASP.NET version 2.0.50727 is set to Allowed in the Web service extension list in Internet Information Services Manager.
    Note The build version of ASP.NET 2.0 may differ depending on what the currently released build version is. These steps are for build version 2.0.50727.

I am sure this will not be the end of problems I encounter however I am off to a good start.

On a side note I would be most interseted in hearing from others running Windows Pro x64 and useful applications such as anti-virus software tht are built for 64bit operating systems.
