Important information about Windows 10 and ACBLscore

In August Microsoft released the Windows 10 Anniversary patch that broke the function keys (F1, F2, etc.) inside ACBLscore. There is now an easier work around to solve this problem.

If you have already followed the instructions to block the Windows 10 patches, we recommend reversing them at this time. Instructions for the new work around can be accessed by clicking the blue box below.


Note: A previous version of ACBLscore® is not needed to install.

Note: The ACBL is no longer producing a DOS version of ACBLscore.
