Margin Master
RockSolid OLEDB driver check and installation from Options tab
Shipped in Margin Master 2026.914.13400 · September 14, 2026
Added a new RockSolid tab in Options that displays the status of the Microsoft.ACE.OLEDB.12.0 driver required for RockSolid imports and provides a one-click Install/Verify button. The startup check now uses a centralized service that properly detects the driver for 64-bit Margin Master.
What changed
Open Tools > Options, go to the RockSolid tab under POS / Connections, and see whether the OLEDB driver is installed. If it's missing, click "Install OLEDB Driver" to download and install it automatically. Windows will ask for administrator permission.
The check for the RockSolid import driver is now more reliable and tells you exactly which version you need.
If the OLEDB driver installation needs a Windows restart or runs into the 32-bit Office issue, Margin Master now tells you exactly what happened and how to proceed.
