Hi everybody,

I'm experiencing some problems installing the ILOG CPLEX Optimization Studio 12.5 fix pack (namely 12.5.0-WS-COS-win64-fp001). On my system I have installed CPLEX Optimization Studio 12.5 x64 on Windows 8 x64, and I am running the fix pack installer as an administrator and setting the compatibility with Windows 7.

During the pre-installation, I get the "Existing installation not found" error, as attached in the image. The installation log just reports that the installation has been canceled by the user: no error is mentioned. Moreover, there's also the line "Search Dev previous versions" reporting that the status is "successful", as if the installer correctly detected the previous installation.

What is the problem?

Regards,

Stefano

I see, thank you for your input. Then the error is probably due to the fact that I installed the Academic edition, while the fix is for the Commercial one. However, I can't find the installer for the Academic edition, neither in the fix central, nor in the Software Catalog of the Academic Initiative. Is it out?

Regards,

Stefano

I experienced the same problem on Windows 7 x64. As the tips did not help, I ended up in installing the fix manually. I cannot recommend this procedure to anybody.

I think, IBM should provide a simpler installer, a one that does not even need Java...

Best regards,

It's a common problem then. How did you manually install the fix? I guess by extracting the installer somewhere and then manually copy/pasting some files into the CPLEX installation directory... Which files? Is there a guide for that?

Well, there is no tutorial for this procedure. I extracted the installer and found the files somewhere inside (they were in serveral folders). I don't even know whether I got all files. At least, CPLEX claims to be 12.5.0.1 now. But I really cannot recommend this procedure. IBM has to fix the installer.

Best regards,

I see. Well, that's nothing we can do about it then. Thank you for your support and let's hope someone from IBM forwards this issue to the developers.

A (more or less) simple way to solve this problem would be to allow to specify the CPLEX-path if the installer does not find it. But nevertheless, I would switch to an installer that does not use java.

If you really want to solve your problem, I suggest you open a new topic specifying the error you have, that seems to be quite different from the one I had. For the records, that got fixed when IBM released a new version of the fix pack that was compatible with the Academic Edition.

As an academic, there should be no need to use the trial version, you can use the Academic Edition. I guess, this won't solve your problem but you won't have any restrictions concerning the problem size.
