I am trying to install cplex on my ubuntu machine.

I have copied the installation file CPLEX_OPT_STUDIO_12.6.1_LNXX86-32.bin to the /opt folder

I followed the instructions from here: http://www-01.ibm.com/support/docview.wss?uid=swg21444285

However, when I try to run the executable, I get the following output:

Preparing to install...
Extracting the JRE from the installer archive...
Unpacking the JRE...
Extracting the installation resources from the installer archive...
Configuring the installer for this system's environment...

Launching installer...

JRE libraries are missing or not compatible....
Exiting....
 

However, when I apt-get install openjdk-7-jre I am told that I already have the newest version of openjdk-7-jre. What am I doing wrong? I notice, that the .bin file is named differently from the one in the instructions mentioned above. Have I simply downloaded the wrong file?

Thanks in advance.

Hello

Are you trying to install a CPLEX 32-bits instance on a 64b VM/Machine ?
If yes, you should use the installer for Linux 64b instead, since it exists now.

Hello Christophe!

I'm installing CPLEX_OPT_STUD_12.6.2_LNX_X86-64 on 32-bit machine, and I'm having the same message error, I'm on ubuntu 14.  my jre is up to date.

I hope you would have any indication or solution to solve it.

Best,

@Cplexer2015 db80fdb8-f9bb-4a35-a7c5-9267ca2b24e2​, it sounds like you're doing the opposite of the original poster.  That is, you'll need the 32-bit installer to install on a 32-bit machine, but you're using a 64-bit installer.

Thanks for your answer, 

Actually they said in the instruction that "This installer can be used on both 32-bit and 64-bit Linux platforms", so if it's the same file for both, what am I doing wrong here?

In your post, you wrote that you're using the installer than ends with x86-64 (that one is 64-bit only).  You need to get the installer that ends with x86-32 instead.  That one will run on either x86 or x86-64 (but always as a 32-bit process).  It's possible that you see a slightly different naming in the place where you downloaded the installer (if so, try the other one).
