Is there a setting in IIS 7.5 to default the "Enable 32-Bit Applications" to False on newly created app pools? I know how to set it for one app pool in power shell, but I'm wondering if there's a global IIS setting for this so it will always be false when a new one is created. Thanks!

False is the default. Are yours getting set to true then? – squillman Aug 2 '12 at 20:30
Yes, on one of our servers all new app pools are getting set to true by default. – Dan Aug 2 '12 at 20:37

The default value for "Enable 32-Bit Applications" is "False" by default. If that is not the case in your setup, you can "fix" it using any of these methods:

Using GUI tool:

IIS Manager | Application Pools | Right click | Set Application Pool Defaults...

Using command line (appcmd.exe in this particular case):

%SystemRoot%\System32\inetsrv\appcmd.exe set config /section:system.applicationHost/applicationPools /applicationPoolDefaults.enable32BitAppOnWin64:"False" /commit:apphost
