FYI I heard back from support; in short, it's normal. "Upon checking internally, the concern you are experiencing is expected and the correct behavior of NetSuite. ODBC Data Source Administrator displays the file version of the driver DLL itself (8.01.00.143) but the version of the whole package/product is 8.10.143.0"

Hi Richard - still unsolved. I also opened a case with support and haven't heard anything.
