Re: Error installing

 looks like you had a previous installation and hence db was not clean.

 

Please clean your db (drop database and re-create) and try again. Alternatively, you can run 

bin/magento setup:uninstall

 which will and try again.

 

Another possible solution is - Might be database was imported before, so delete it and re-installed it for the same.

Re: Error installing

Sometime when u uninstall it doesn't remove DB entries as it might be in use somewhere. Its better you go to phpMyAdmin and "Drop" your DB and then start the re-installation of M2.

 

Hope this help.
