Welcome, my name is Dustin and I will assist you today!
Sometimes an archive and install, or any install will error out.
should not have taken so long to complete.. Two hours, max.
What you can try to do, is hold down the power button, shut the mac down.
and then, start it and attempt the install again...
If your archive install fails twice.. Then if your trying to save
your files.. Your best bet is to use a second mac..
Take this first mac your trying to repair, boot into target disk mode, connect your other mac, and then manually copy all the files you need. And once thats done.
Perform a normal clean install on the mac.
Heres a bit about target disk mode.http://support.apple.com/kb/PH10725
