Thanks for the replies. I'm curious what is the definitive factor about a software that allows it to be on a non main drive or not? Myself ,Ideally, would like to put all of my music software on an external drive as I use the same p.c. for everything. .....I guess I'll ask (with the risk of being shamed) anyone run sonar from a separate drive? (I know this is the wrong forum to ask such a question but I do own nearly all of p.g.s programs too:)

...........Jeff......
