If you get the error ‘The ‘Microsoft.ACE.OLEDB.12.0′ provider is not registered on the local machine’ when trying to report new timesheet to database or running OLAP Statistics, this usually means your system does not have the one or more of the data connectivity library for Microsoft Office (Microsoft Access Database Engine). This can be easily fix by downloading from the Microsoft Download Center site. You may need to choose the correct the setup version (32 bit or 64 bit) based on the bitness of your Microsoft Outlook.
