I am getting the following error when I try to run cplex on Ubuntu 10.04 x64.

Error 32201 ILM Error 16: CPLEX: license file not found or unreadable.

but, I am not getting error when I try to run cplex on Ubuntu 9.10 x64.

Preview Edtion can not run on Ubuntu 10.04 x64?

Did you install the license file on the 10.04 box? (Or are you using a network license?) Did you set the environment variable that tells CPLEX where the license is? Did you confirm the export (say, run CPLEX in a shell)?

Thank you for the reply.
I have not set up installation of a license, and environment.

Is a license required of Preview Edition (Trial)?
(There were no documents about a license)

I tried installation of the 32-bit version CPLEX
in the same machine(Ubuntu 10.04 x64).
(binary:cplex_studio12301.prev.linux-x86-32.bin)
As a result,I am not getting error.

Then, I installed the 64-bit version CPLEX once again.
It became impossible for me to get an error.

Mmm.
Although a reason is not known,
since it became impossible for me to get an error, this thread closes.
Thank you.
