The Desktop SDK 15.0 installer includes redistributable merge modules and installers for the latest versions of QBFC15, QBFC14, and QBXMLRP2. In order to minimize the size of the Desktop SDK 15.0 installer, we did not include redistributables for older versions of QBFC. Note that Intuit did NOT release a QuickBooks SDK Version 9 or QBFC9. Please note, 64-bit SDK is only available for QBFC15 and QBXMLRP2.
Note: There might be some broken links in QBFC14 and lower. We recommend you use the latest version.
In case you need an older version, here are links to archived versions:
