Yes.  Locate zlib0 in the package listing, and click on the spinner in 
the "New" column until it says "reinstall".

An install shouldn't take 12 hours, unless you tried to install 
everything and you have a slow network connection.  If you still have 
/var/log/setup.log.full from that install, I suggest you take a look at 
it and see if you can tell why the install took so long.

If you aren't able to resolve the issue and have to write again, please 
attach cygcheck output as explained here:
