Installation of v3 went fine... Tried to open the Store solution and get the following "Unhandled Activation Error" and to contact Xamarin Support with the following information:
System.UnauthorizedAccessException: Access to the path 'C:\ProgramData\MonoTouch\License\monotouch.trial.licx' is denied.
at Xamarin.Components.Ide.Activation.ActivationService.GetErrorWorkflow(LicenseSyncResult results, Boolean ignoreSyncErrors)
at Xamarin.Components.Ide.Activation.ActivationDialog.DisplayWorkflowStep(ActivationWorkflowStep step)
at Xamarin.Components.Ide.Activation.ActivationDialog.<>c__DisplayClass13.b__12(Task t)
I had a trial of an older version awhile back... is it possible this is preventing me from trying the new version?
