Desktop Client: Requirements for importing data from Microsoft Excel (Generator won't read 64-bit Office Excel) xlsx files

iGrafx 2009 (version 13) and later uses the 32-bit Microsoft Access Database Engine drivers for importing data from Excel documents (*.xls and *.xlsx).  These drivers are typically installed with Microsoft Office.  In order for the Generators (or iGrafx in general, including Import Database Data) to read data from *.xlsx files you need the Office 2007 versions or later installed.  Additionally, if you have a 64-bit version of Office you will need to install the 32-bit drivers separately because they are not included with 64-bit versions of Office. 

The 32-bit data access drivers for Excel are available from Microsoft; e.g. as a free download here:  http://www.microsoft.com/en-us/download/details.aspx?id=13255

If you already have 64-bit Office installed you must install the 32-bit drivers from the command line using the switch "/passive" excluding the quotes.  The download is currently named "accessdatabaseengine.exe" so from the command line you run this:  accessdatabaseengine /passive
