I am running Windows XP Professional x64 and IIS 6.0. I have been tasked with making some code changes to a classic ASP application. I've created a virtual directory under iis. I get the following message when I try to browse to the site.

You are not authorized to view this page The URL you attempted to reach has an ISAPI or CGI application installed that verifies user credentials before proceeding. This application cannot verify your credentials.

I'm checking the production server to identify this issue and I'm thinking it's related to the framework setting. It is set to 2.x on my local 64 bit machine and the 1.x version does not appear in the dropdown list. I've installed 1.x on the machine, but now the tab no longer appears. I did some research on how to get the tab to reappear, followed the recommendations. The tabl now appears, but 1.x framework is still not listed.

Any suggestions are greatly appreciated. Are there command line arguments to tell the IIS to run this site under the 1.x framework since I can't seem to do it from within IIS?

You have to switch to 32bit mode, like this: It is per-process, so you will not be able to run other web applications in 64bits.

That is the article I found and I ran those steps. Now I don't have an ASP.Net Tab to switch the app to run under v1.x. I believe it is still trying to run under 2.x. – Iceman Jan 25 '10 at 21:19
I ran into a variety of issues, including needing the FrontPage extentsions. I ended up making a VMWare Image with XP Pro 32bit, setup IIS with the appropriate security, and then installed the Frontpage extentsions. I have it up and running, but now the real fun begins. Thanks, Randy – Iceman Jan 26 '10 at 17:36
