Confluence has failed its initial bootstrap

[Yaw Ababio]

Confluence will not startup and I'm receiving the following error when I try to upgrade; "

Upgrader issue: error occurred when parsing your installation directory".

Tried start Confluence with URL:
http://localhost:8097/bootstrap/selectsetupstep.action

Seen on screen:
