We tried this as well, couldn't get it to work, so reinstalled the 33 bit OS and it works, seems a shame to lose all that extra memory,
but until we can all find a driver we are stuck on 32 bit.
its the advantech driver that causes us all the errors.
I did hear a rumour that it can be done, but have yet to try myself
If you email Phil who works for transplan UK, he maybe able to give you more information on this,
as he told me it could be done a few weeks after we did our re-install!
Good luck and keep us all updated !
