OSD CCM Client causes error

Hi,

i have a OSD set up for my travel mate 6594 machine that currently only install Windows 8.1 32bit and the SCCM client. This works with no problems however when I try changing it to a 64bit OS ( ive tried win8.1, 8 and 7) after applying the image and when it tried to install the SCCM client it crashes saying OSDSetupHook.exe - Aplication Error the error says The instruction at *number* referenced memory at *numbers*. the memory could not be read. I have installed a 64bit os manually on this machine previously without problems.

My server is 2012 and SCCM is 2012 sp1 v5.07804.1400

Thanks

Mike
