I am having problems using the ANSYS LIcense Manager in CFX-5.7.1 on Linux x86_64.
This is because only the 32bit license manager installation was shipped with CFX-5.7.1,
which installs correctly, but the scripts to launch it realises that
they are running on x86_64 and cannot find the 64 bit executables. It
then defaults to the non-gui license manager.
The fix to get the gui to work is to change line 173 in
SYSDIR="linop64" to SYSDIR="linia32".
