I have forgotten my username and password of admin in MarkLogic 5. I tried to uninstall the software MarkLogic 5 and install that again. But every time it is asking for username
The default data directory is under C:\Program Files\MarkLogic. Remove c:\Program Files\MarkLogic\Data directory and start ML, then run MarkLogic Admin url, which will open the url to http://127.0.0.1:8001/ It will ask initial setup. Type your new admin password there, then you will be cool bananas!
