IIS Advanced Settings

Question

Usually, for a service in IIS 7, there should be an option of 'Enable 32-bit Applications' in the General Category of Advanced Setting. However, in my IIS 7, there is no such an option. The Advanced settings interface is different from one of my co-workers'. Can someone explain it? How can I get the 'Enable 32-bit Applications' option? Thanks.

You have to be running on a 64 bit machine to see that option.

My CPU's OS is a 64-bit OS. What setting I should do to enable it? Thanks.

Are you looking at IIS 6.0 Manager or IIS Manager?

You can try running a command line to turn it on,

appcmd set apppool /apppool.name:MyAppPool32bit /enable32BitAppOnWin64:true

However, the only reason I have seen it not be there is when you are not on a 64 bit machine.

Ryan: Thanks for your post. In which directory I can run the commandline: appcmd set apppool /apppool.name:MyAppPool32bit /enable32BitAppOnWin64:true?

I believe any command line. You may need to search for appcmd if that doesn't work.

Referring to Ryan's post, I did the followings:
1) Start AppCmd.exe – At the Command Prompt, type cd %windir%\system32\inetsrv, and then press ENTER.
2) Change an Application Pool for an application.
3) In IIS Manager, Enable 32-bit Applications on the Application Pool Defaults.
This solution should be credited to Ryan. Thanks to Ryan.
