Q: How can I download and install the ACDS v11.1?
A: You can download and install the ACDS v11.1 from the Altera Download Center (www.altera.com/download) with the following options:

Altera Installer
The Altera Installer is an on-demand installation manager that allows you to download and install Altera software using the GUI or command-line method. An Internet connection is required during the download and installation process. The Altera Installer supports both Windows and Linux operating systems.

Individual Software Files
Individual software files are self-extracting installation executable files. These files are named in the format of <version>_<product>_<windows/linux>.<exe/sh>. For example, a Quartus II individual software file is named as 11.1_quartus_windows.exe or 11.1_quartus_linux.sh.

When the individual software file is run, it will self-extract to a temporary location. The Altera Installer will then install the individual software. An Internet connection is not required during installation as compare to installation using just the Altera Installer. The individual software files are available for both Windows and Linux operating systems.

You can refer to the About Installing Altera Software (Quartus II Help) for instructions on how to download and install the ACDS version 11.1 using the options described above. You can also refer to the Altera Software Installation and Licensing (PDF) manual for more information on installing and licensing Altera software.

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

This specification also applies to the Destination Directory that you specify in the Altera Installer.

Q: What is MD5 sum value and what is it for?
A: 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 Altera 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 in the internet (e.g. winMd5Sum) to verify your downloaded Altera software with the provided MD5 sum value.
