Hello,
(excuse my bad English)
I did all steps with installation and when click on authserver.conf or worldserver.conf I get 0x000007b - I reinstalled core and used MySQL 5.6 - again this error, after this I used 5.5 and same this error.
I'm use:
Windows 8 Pro
machine with 6gb RAM 1TB HDD 1gb video card
installed VIsual studio 2012, get GetExtension, Heidisql ( showed in http://collab.kpsn.org/display/tc/How-to_Win Cmake 2.8.12
OpenSSL v1.0.1f , and another thing when I installed MySQL I didn't see Launch the MySQL Instance Configuration Wizard, re-isntaled it around 5-6 times and again didn't see it.
