I have CPLEX 12.2.0.0 installed and running on two machines (PC and laptop), both of which have Linux Mint (fork of Ubuntu) as the OS. On neither machine is the CPLEX directory tree part of the system path (I've aliased 'cplex' to the correct command with full path). I've attempted to install the fixpack for 12.2.0.2 with mixed results.

On the PC, it installed fine, and running CPLEX now gets me version 12.2.0.2. In particular, the installer was able to figure out where CPLEX 12.2 was installed. I'm not sure how (that's why I mentioned that it's not on the search path). On the laptop, the installer tells me that it's installing to NULL, and acts as if it has installed successfully, but the CPLEX 12.2 directory tree is unaffected (so I'm still running 12.2.0.0), and I can't find any trace of an installation anywhere (not even the installer log file).

My guess is that there's a way to specify the installation path to the installer, but the command line help for the installer was unhelpful. Anybody know the secret handshake?

Paul,

I get the same behavior that you are seeing when I install into a directory and then move (mv) it.

The file in your $HOME which records the installation information is .com.zerog.registry.xml. When I installed the fix pack after moving the original install directory and installed into NULL, the .xml file records that I did an update. I moved the directory back and tried the update, but it did not work. I think you may have to start over with the 12.2.0.0 installer and then apply 12.2.0.2.

Rodrigo and Mary,

Thanks for the help. I've got it sorted now. I didn't have to reinstall 12.2.0.0; I just edited the registry file, deleting any reference to 12.2.0.2 (which apparently had installed somewhere in /tmp, only to be automatically hosed at logout) and corrected the paths on all the references to 12.2.0.0. Then I reran the updater and it worked.

Much obliged,
Paul
