Both an updated 32-bit and an updated 64-bit installers are available on the TDP Community website: http://www.toadworld.com/products/toad-data-point/toad_data_point_beta_program/default.aspx
Reminder: A 64-bit installer is for use ONLY on systems that already have a 64-bit IBM client. All other environments should use the 32-bit installer.
