If you plan to run 32-bit applications on 64-bit Windows, you must configure IIS to create 32-bit worker processes. On 64-bit Windows, 32-bit processes cannot load 64-bit DLLs, and 64-bit processes cannot load 32-bit DLLs. IIS 6.0 using WOW64 is intended to run 32-bit personal productivity applications needed by software developers and administrators, including 32-bit Internet Information Services (IIS) Web applications. Windows Server 2003 TM, Service Pack 1 enables IIS 6.0 to run 32-bit Web applications on 64-bit Windows using the Windows-32-on-Windows-64 (WOW64) compatibility layer. Running 32-bit Applications on 64-bit Windows (IIS 6.0) Oops! - And here is the info from the 'horses mouth' at TechNet. NET 1.1 ASP.NET in 圆4s IIS6 (which runs in 32-bit mode):Ĭscript %SystemDrive%\inetpub\AdminScripts\adsutil.vbs set w3svc/AppPools/Enable32bitAppOnWin64 1 If you run the following command in Command Prompt, you will be able to use. Turns out there's a script mod you can make (the only place I found this is here.) One thing I was worried about, though, is how do you get ASP.NET 32 bit support in IIS 6.0 - which is now 64 bit! Uh-Oh! Windows Server 2003 圆4 edition is so cool, now that I have a new 64 bit AMD machine to play on.
