Answer 2

The path of the Google SiteMap Generator Module was set incorrectly by the installer on Windows Server 2008 running 64bit OS.

C:\Program Files (x86)\Google\Google Sitemap Generator\\IIS7_Module_x64.dll

Notice the slashes before the name of the dll file.

To correct the issue do the followings:

• Click your server name in the IIS Manager
• Click ‘Modules’
• Select an entry named like ‘GoogleSiteMapGeneratorModule’ and click ‘Edit’
• Replace the double slash with a single slash in the path field
• You might need to reboot the IIS
