MS Access was a popular choice of databases for low volume websites as it avoided the complexity and expense of using MSSQL. Whilst this was fully supported on Windows 2008 (32bit) and earlier it is now depreciated in the 64bit Windows 2008 R2 / Windows 2012 environments that we now provide. If you have a specific need to use MS Access we can optionally switch your application pool to 32bit mode which will enable MS Access support but please note that is provided with limited support as it against current best practice. We recommend that customers transition to MSSQL which is now included with all of our Windows hosting packages as standard.
