I’m currently performing some work on classic ASP pages that during development are retrieving data from an existing Microsoft Access database. After receiving the following error I found that Microsoft haven’t and have no plans to release JET OLE DB drivers for 64-bit platforms. Fair enough it’s hardly the way of the future but I wanted to be able to perform some development on the pages before migrating to SQL\/Server.<\/p>\n

\nProvider cannot be found. It may not be properly installed. <\/p><\/blockquote>\n

After some digging around I found the solution was to change the IIS 7 settings to run the application in 32-bit mode. That can be performed under Vista x64 using the following steps:<\/p>\n

  • Click Start > All programs > Administrative tools > Internet Information Server (IIS) Manager\n
  • Under the machine name click on Application Pools.\n
  • Right-mouse click on DefaultAppPool and select Advanced Settings…\n
  • Under the general section set “Enable 32-Bit Applications” to true.\n
  • Press OK and IIS should now be running in 32-bit mode, no other actions are necessary.
