Installation is incomplete error at 99 percent but when i login to admin panel its working fine .what i next to do ?any one kindly state the issue?
have you checked with url ? - sometimes it showing 99% due to few configuration of server , but magento 2 is already installed.
so check with the url you have setup magento2 , also check admin as well.
if its not works then post the error log here , so its help us to troubleshoot the issue.
