I realize this is quite old, but having run into the same issue myself, wanted to post my own workaround here to hopefully help some other poor soul.
Background on this issue is further discussed at the location below (tried to post there, but cannot due to the thread being locked, and anyway that thread leads here): http://ubuntuforums.org/showthread.php?t=2070693 Anyway, I am not actually running Ubuntu, but rather Debian Wheezy i686 32bit. My problem was exactly as discussed here, and I can only assume my solution would likewise work in Ubuntu. Since the version of zlib included with the Guitar Pro 6 package was apparently too low, I thought I would try copying the newer version of zlib in its place in the GP6 installation directory. Turns out this works. What I did: sudo mv /opt/GuitarPro6/libz.so.1 /opt/GuitarPro6/libz.so.1.bak sudo cp /lib/i386-linux-gnu/libz.so.1.2.7 /opt/GuitarPro6/libz.so.1 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1067557 Title: zlib1g 1.2.7 and libxml2 2.8 too new for each other?
