AddInReloader Rtd Issue

In this case, my "master" addin is unable to fully unregister the current "slave" addin (ExcelIntegration.UnregisterXLL(path)) so that subsequently trying to delete the current slave xll produces a System.UnauthorizedAccessException. Strangely, it allows me to rename the slave xll file to slave.backup but then when I register the new slave addin (RegisterXLL(slave)), it actually registers slave.backup again.
