Installing Quartus and ModelSim

[Altera_Forum]

Hello, 

 I am new to the products and am the SA who is installing them on a LINUX server. We run on a closed network so I downloaded the 2 products we have purchased (Quartus and ModelSim), moved them via DVD to the server. I gunzip and untar the downloaded files and used the altera_installer.external.sh to start the install. The install works but my issue is it will only install one product and when I try to install the other product I received the following error: the directory does not contain the modelsim-altera edition - installed installers. specify a valid installer directory. In this example, I installed ModelSim, ran the update command (altera_installer_cmd --update --gui), choose to modify the installation, marked Quartus, install directory (/12.1_177_quartus_linux), browsed to destination directory and after hitting next received the above error message.  I'm assuming by directory structure needs to be different but I'm not sure what to change. I have both the 12.1_177_quartus_linux and the 12.1_177_modelsim_ae_linux in the same directory /Altera/ver12. The documentation makes it sound like you can add components to an installation.  Thanks for the information.

Hi, I had similar message on Windows 

 It happens when you try to install a service pack only. It looks for a valid Modelsim directory. install modelsim complete version first (near 700mb), and then install modelsim service pack.  Have a look at ModelSim Altera starter Edition which is free with limitations.

Thank you for the reply. I haven't had a chance, until today, to look at this install again. I thought I did download the complete version of ModelSim and Quartus. I can install each separately but once one is installed it does not allow me to update the install to include the second product. Here are the names of the files I downloaded: 

Quartus II Software (12.1_quartus_linux.tar.gz) ModelSim-Altera 10.1 Software for Quartus II Software Verstion 12.1 (12.1_modelsim_ae_linux.tar.gz Altera Design Suite V12.1 for Linux (Altera Installer)
