I know there are numerous quirky things with promotion manager (4.0) but for the most part we can manage. I have used it numerous times and never seen this error and do not find any info on it.
Promotion Status=Failure : Application not available
All I am doing is trying to promote two crystal 2011 reports only, from our dev to prod, they do not exist in prod. All the services are running fine, What does it mean with application not available? I have the nice green check box on my connections to each environment. Any help is appreciated!
