I installed Maple 11 on an AMD64 (X86_64), Debian Linux machine. The installer seems to work fine, but maple does not work: psz@potenza:~$ /usr/sms/share/maple/11/bin/maple Maple initialization error, invalid license return code psz@potenza:~$ or maybe psz@potenza:~$ /tmp/11x/bin/maple Maple initialization error, Signal received during initialization: UNKNOWN (13) psz@potenza:~$ I suspect that this error is caused by the installer creating some 32-bit binaries (that cannot work on a 64-bit machine): psz@potenza$ file bin.X86_64_LINUX/* | grep 386 bin.X86_64_LINUX/libjogl.so: ELF 32-bit LSB shared object, Intel 80386, version 1 (SYSV), not stripped
