I downloaded atlassian-confluence-5.6.5-x64 and ran it.
It occurred error and stopped, so I downloaded it again. This time, I saw the message that server and host(??) are already being used. I deleted all the applications and tried it again.
While installing, I saw the download location and upgrade message. I did it.
That is all. It looks like upgrade is completed but I cannot see anything.
I am not sure if you understand my questions or not. Anyway, how can I install and use this trial version??
