Came a day early in the UK because of postal strike tomorrow. Very easy new install from vista 32 bit after I found out how to change the bios to boot off the dvd, remember to format the disc by clicking on drive options (advanced) or you will end up with a dual boot system. TWS keeps asking for javaw.exe when it is run, hopefully it will remember this now. Ninjatrader 6.5 works as normal. Managed to lock up doing a windows update while running TWS, ninjatrader, chrome and streaming music. Otherwise very similar to vista which I never had a problem with.
