Hi, You need to install the 32 bits compatibility libraries: sudo apt-get install ia32-libs
For skychart you can also build a 64 bits version from source but in this case do not use the lazarus compiler from Ubuntu because this is a too old version, get lazarus 0.9.28 from http://www.lazarus.freepascal.org/ I not build 64 bit version regularly because I use a server with an old processor for the automatic build. You select the 64 bit version of Ubuntu at the time you download the CDrom. But this is the good choice and all must be OK after you install this compatibility libraries. Patrick
