Could you please explain a little bit more about what you are doing?
I am not familiar with these terms, sorry:
created an AMI from a deadline empty windows template
saved AMI
spot instances
I am guessing your are setting up some virtual machines rather than physical computer. If that's the case, can we assume that it should work in a similar way as setting up Corona on multiple physical computers?
If so, can you please let me know on how many computers you need to activate Corona?
Also, can you share your registered email address with me? (via a private message)
I would like to check whether this is something like "there is a license but Corona does not see it for some reason" or maybe "not enough available licenses".
