For information, flash.ocx, doesn't exists in Z:\opt\HyperSpin\, I think windows should load it from windows/system32/Macromed/Flash/Flash32_23_0_0_207.ocx
Did you try copying that file into the program folder and trying again?
Try again in a clean prefix by using winetricks to install Flash and after that install the program, Flash could have other dependencies and may not have been installed correctly, winetricks handles that.
