 Hi Tim,

I am saying, as a user of MS4W you will likely not notice any changes 
(in fact, as you can read in the OpenFileGDB driver page, in the section 
"Comparison with the [Esri] FileGDB driver' 
http://www.gdal.org/drv_openfilegdb.html) you will be able to access 
(read) more versions of FileGDB data with this driver.  The only issue 
is that you will not be able to use GDAL (such as through an ogr2ogr 
command) to generate a new .gdb geodatabase/file).

If you still don't follow me, goto your command prompt window and follow 
my steps:

  - cd ms4w
  - setenv.bat
  - ogrinfo --formats

That command lists all vector formats that are available in your version 
of MS4W, on your machine.  Notice that for each result, there are some 
brackets, such as "(rw+)" or "(ro)"; the first meaning that you can read 
and also write that format, and the second meaning you can only read 
that format.  You'll notice that many formats are read-only (maybe you 
never realized this before).

So give a re-read to my initial message, and invest some time in reading 
the driver page for any format that you are using (in this case 
http://www.gdal.org/drv_openfilegdb.html).  It may be that for your case 
you need write access (to generate new .gdb files), in which case you 
can contact/nudge the Esri support team directly, and ask when their 
next FileGDB SDK is going to be released - I had seen a thread last year 
where an Esri support person said "likely mid-2015".  So until then, 
we'll use this GDAL-reverse-engineered SDK :)

Maybe this is too much information for you through email - of course I 
am available for providing professional training on these tips, for your 
organization.

Thank you for using and supporting MS4W, it is your financial support 
that helps maintain such an innovative solution.
