%windir%\Microsoft.NET\Framework\v4.0.30319
%windir%\Microsoft.NET\Framework64\v4.0.30319 (on a 64-bit machine)

Run IIS in 32-bit mode on a 64 bit machine

To configure ASP.NET to run in 32 bit mode on a 64 bit server.

On IIS6, open a command prompt and type following command and press ENTER.

cscript //nologo %SYSTEMDRIVE%\InetPub\AdminScripts\adsutil.vbs set w3svc/AppPools/Enable32bitAppOnWin64 1

On IIS7/7.5, open a command prompt and type following command and press ENTER.

apppool /apppool.name:MyAppPool32bit /enable32BitAppOnWin64:true

Grant Permission to DefaultAppPool Identity

After upgrading web applications to IIS 7.5 on Windows Server 2008 R2, you might get following error.

Access to the path ‘d:\site\cache.txt’ is denied.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.UnauthorizedAccessException: Access to the path ‘d:\site\cache.txt’ is denied.
ASP.NET is not authorized to access the requested resource. Consider granting access rights to the resource to the ASP.NET request identity. ASP.NET has a base process identity (typically {MACHINE}\ASPNET on IIS 5 or Network Service on IIS 6) that is used if the application is not impersonating. If the application is impersonating via <identity impersonate="true"/>, the identity will be the anonymous user (typically IUSR_MACHINENAME) or the authenticated request user.
To grant ASP.NET access to a file, right-click the file in Explorer, choose "Properties" and select the Security tab. Click "Add" to add the appropriate user or group. Highlight the ASP.NET account, and check the boxes for the desired access.
