So last week I was just finishing of a generic metadata import solution for MDS. Basically you map your Excel semi-structured data source file to the entities and attributes in MDS run the solution and it automatically imports, transforms the file and loads it through to the mapped entities. It was all working great; until Windows installed a patch! Basically it looks like they have finally nailed the coffin shut on the Jet 4 driver – to be fair I probably shouldn’t have been using it.
So for older xls files (2007 – 2010) you can use the Microsoft.ACE.OLEDB.12.0 driver. If you have office 64 bit installed like me your SSIS IDE may not have this driver available in SSIS; but why?
Well because the IDE requires the 32 bit driver. You can flip the debugging run time in SSIS to be 64 bit however the IDE requires the 32 bit in order to design time validate the component and the solution can’t run in 64 bit until it’s validated; which is a tad annoying.
You can install the 32 (& 64) bit drivers from here. The really annoying thing is that if you have office 64 bit installed it won’t let you install the 32 drivers. This is the workaround cmd:
