How do I uninstall Intel FPGA software?

To uninstall Intel FPGA software, please refer to the “Uninstalling Software” section in the Intel FPGA Software Installation and Licensing Manual (PDF).

Can I use spaces, special characters, or non-English characters in path names?

No. You must use only alphanumeric characters and do not use special characters, or non-English characters, such as " \ / : * ? " < > |",in the Installer Source Directory box. However, spaces are permitted. This specification also applies to the Destination Directory that you specify in the Installer.

Can I run an anti-virus software when I download and install Intel FPGA software?

Some anti-virus scanner can prevent the Installer from downloading and installing software files to your machine. Thus, we recommend that you disable any anti-virus or malware scanner before the download and installation start.

Refer to KDB rd07222010_954 for more information.

Can I install Intel FPGA software via command line?

Yes. You can install software for Windows or Linux at the command line with a custom installation script using command-line arguments. For more information about installing software via command line, please refer to Installing Software at the Command Prompt. Please ensure you have sufficient disk space at your targeted installation drive before you start your installation.

Can I install specific device families at the command line?

No. Currently you can only install device families through the Quartus Prime software graphical user interface (GUI). Please refer to the Quartus Prime Software Download and Installation Quick Start Guide on how to add additional device families to an existing installation of Quartus Prime software.

I tried to download the individual software files, but the files are too big. The time to download these files is too long and the downloads always fail while in progress. Is there any way to work around this?

If you are on the Windows OS, on the software download page, click the Individual Files tab and for the Download Method, select Akamai DLM3 Download Manager. The Akamai download manager will install on your machine. Once installed, the download manager will manage your downloads and resume them if there is an error. If you use the Linux OS, the Akamai Download Manager is not available, however, you can download the Linux files on a Windows machine. On a Windows machine, change the Operating System selection to Linux and then download the files. Once the download is complete, you can transfer the files to your Linux machine.

Why do I still get the “error connecting to the Internet” error message even though I have a working Internet connection and configured my proxy setting correctly?

You might be connecting to a NTLM proxy type. Please check with your IT administrator. If you are behind an NTLM proxy, please refer to Downloading and Installing Software at the Command Prompt for instructions on how to download and install software behind an NTLM proxy. Note that only the command-line installation method supports NTLM proxy.

What is MD5 sum value and what is it for?

MD5 sum is a string of letters and numbers that acts like a fingerprint for a file. If two files have the same MD5 sum value, then the files are exactly alike. You can use the MD5 sum values provided for each software download to verify your downloaded file if it is the same as the file in our servers. To do that, you can use any MD5 sum checker tool that is available on the internet (e.g., winMd5Sum) to verify your downloaded software with the provided MD5 sum value.

Where can I find the older releases of Quartus Prime software installation files?

You can find and download the older releases of Quartus Prime software installation files from the download center web page.

Can I add other software tools after installing the software?

Yes. Please refer to the Installing Support for Device Families and Other Software section in the Intel FPGA Software Installation and Licensing Manual (PDF) for more information.

Should a Quartus Prime Sofware Update installation be performed over an existing Quartus Prime software installation or can it be installed as a new full installation? (e.g Do I need to install Quartus Prime software over the pre-installed Quartus Prime software)

Yes. You must install the Quartus Prime software version before installing the Software Update. Otherwise, the update will not be installed correctly and the Quartus Prime software will not run properly.

For individual software files installation, which directory should I Install my software to when multiple software are installed?

All of the individual software (e.g. Quartus Prime software, ModelSim*-Intel FPGA software) should be installed to a common parent directory. For example, both Quartus Prime software and ModelSim-Intel FPGA software directories should reside in C:\intelFPGA\<Intel FPGA software Version>.

How to add additional device families to an existing installation of Quartus Prime software?

Please refer to the Quartus Prime Software Download and Installation Quick Start Guide on how to add additional device families to an existing installation of Quartus Prime software.

Windows

Why does the individual software file download fail with the Internet Explorer 6 or the Internet Explorer 7 browser?

You might encounter problems when downloading individual software files of sizes above 1.8 GB from www.altera.com when you are not using the Akamai download manager. This is due to a known issue with the Internet Explorer 6 or Internet Explorer 7, and large file downloads. Some of the problems that you might encounter include cyclic redundancy check (CRC) errors, corrupted download files, or incomplete download files.

Can I specify a UNC path as the target install directory?

No. The Installer does not support UNC paths. Alternatively, you can map the UNC path to a drive letter and specify it as the destination directory instead.

Why are there extra files left in my C drive after the Intel FPGA software installation?

The files left in your C drive are Microsoft VC8 redistributable files from ModelSim-Intel FPGA software installation. The package is required for ModelSim-Intel FPGA software installation. However, these files are safe to delete after the installation. Please refer to KDB 10312010_553 for more information about these files.

I have installed Intel FPGA software into C:\Program Files\intelFPGA. I use Nios II EDS. Upon launching the program from start menu entry "Nios II Software Build Tools for Eclipse", why does the list under File > New > "Nios II Application and BSP from Template" appears to be empty?

You might have installed Intel FPGA software into a path with spaces, in this case, it's C:\Program Files. Please install Intel FPGA software into a path without spaces. For example, C:\intelFGA.

Do I need system administrator privilege to install Intel FPGA software?

Yes. Administrator privilege is needed during the installation process.

How to extract the installation files from the TAR archive format in Windows?

Please refer to the Quartus Prime Software Download and Installation Quick Start Guide on how to extract the installation files from the TAR archives.

Linux

How can I specify the destination directory if I cannot browse to a specific directory?

This is a known issue for some operating systems. If this happens, you can manually type the destination directory path into the Destination Directory box.

Why do I get the following message when I start my Quartus Prime software?
“quartus_map: error while loading shared libraries: <path to quartus/bin>/libcd_err.so: cannot restore segment prot after reloc: Permission denied”

This is a known issue for Quartus Prime software running on a Linux OS with SELinux (Secure Enhanced Linux) firewall installed. Please refer to KDB spr329499 for the workaround.
