Hi all, I am not sure that I did the right thing to install Ship Sim Extreme into the Program files X386 rather than Program files, which would then make it 64 bit and using all of my 4 gig's of memory. In the X386 program files it is in 32 bit system and can not use all the available 4 Gig's but only 2.89 or so according to the tech guys. Should I uninstall the Ship sim from X386 and reinstall into the Program files 64 bit space? Your help would be appreciated. Regards Peter
