What is the required available Memory for installation of MSTS? I am looking at running it off an external hard drive. Brad
dont really know but if you are going to use an external, you will have plenty of room if it is empty to add all the extra MSTS routes and stuff. I deleted it from my puter as my machine is technically dated for operating MSTS the way that it needs to operate. I can still run the program but not like it should be done as the graphice as slow on my machine. I think that the basic is about 2 gb or less with the complete install.
