The product name is now changed from NotesSQL to IBM ODBC Driver and is available https://www.ibm.com/developerworks/lotus/downloads/toolkits.html

I can also tell, for someone like me just completed ODBC setup, Notes 32-bit Notes 9.01 and IBM ODBC (also 32-bit) 9 drivers (former NotesSQL), these hints here, also helped me:

Notes 8.5 - ODBC issues

which referred to this tip:

Notes ODBC Driver - Install, Configure and Testing

Cheers

This link should take you to the download for the NOTES 9 odbc driver for Lotus Notes 9 Social Edition.

Has anyone found anything definitive from IBM stating compatibility? The Supportability Q&A about Notes and Windows 10 page talks about other software, but not the Notes SQL 9 driver.
