System Error when running Ganache 1.1.0 on win32

[theivanfranco]

I believe I had two instances running. Might be helpful to add additional port numbers for multiple instances?

PLATFORM: win32
GANACHE VERSION: 1.1.0

EXCEPTION:

I (also) stumbled across this when I fat-fingered the Ganache icon, and tried to launch twice. It seems reasonable that the ability to run two instances would not be implemented, but I bet there is a nicer way to fail? Maybe a nice message to the user "It looks like you have Ganache running in another window" or similar.

Thanks so much for reporting this! This issue will be tracked using #665. I apologize for the catch-all comment. I will be going back through these issues and make sure I don't miss any specific details and make the appropriate comments.

Hey @if1999615 and @zachlysobey! Unfortunately we do not support running multiple instances of Ganache simultaneously currently. They share the same Settings file which will mean they'll both try to run on the same port.

We're still determining whether or not we'll support multiple instances (see #684), but we're currently working the "nicer way to fail"! Thanks for the feedback
