Before I install this can some one tell me if the mechanism for licenses will change with R2 ?
We develop everything in VM's these days and it's a real PITA having to get a license that is keyed to an ip or mac as these are not fixed and change constantly. I tend to use demo licenses now as it's easer and quicker than trying to get a dev licenses every few days.
No, and I haven't heard of this specific problem. Why is your VM switching MAC adress ?
