  32 bit and 64 bit application pools Reply Contact Hi all,  I'm new to using IIS7 and have come across an issue with a migration that I am carrying out. I have a SharePoint public facing site which runs a number of web applications below it. At the moment my SharePoint site is running as expected. I need to run the web applications that run beneath it using a 32bit application pool as they connect to MS Access. At present when configured as standalone applications they seem to work using the application pool. When I try to add them as a web application beneath the SharePoint site all I get returned is a blank screen in IE. Has anyone encountered problems with this and could maybe help me out.  EDIT*** I've turned on show friendly http errors within IE and the error is now "HTTP 500 Internal Server Error" and the website cannot display the page. I've since turned on the Failed Request Tracing capabilities, and got further with tracking my error. It now appears I'm getting the following: %1 is not a valid Win32 application. The application is a 32 bit app so should not return this error. As stated previously when being executed as a web site on its own it works as intended. Hopefully this is possibly more help.  Thanks in advance, Grant

  Re: 32 bit and 64 bit application pools Reply Contact Hi Grant, SharePoint has global level IIS extensions which can affect all applications. As 32 bit application cannot load such 64 bit extensions, 500.19 error can happen. I suggest your team Get rid of Access and migrate to SQL Server Or check with SharePoint experts to see if there is a way to disable the extensions for your 32-bit application.

  Re: 32 bit and 64 bit application pools Reply Contact Thanks for the response and apologies for taking as long to get back to you. Getting rid of access is unfortunately not an option (I wish it was but nothing I can do regarding this). I did have another though relating to redirection. The applications work on their own so I was thinking after coming across the HTTP redirection option in IIS7. Could I redirect a page to another website, either on adifferent port, or using port 80 with a differnent header. How would this look to users accessing the site externally?  Thanks in advance.
