I tried installing from the CD installer and also downloaded it from Altera website but the same error shows. These are the errors:    Traceback (most recent call last):    File "d:/SJ/nightly/12.1/177/w32/work/installers/windows32\build\pyi.win32\altera_installer_gui\outPYZ1.pyz/process", line 137, in start    File "d:/SJ/nightly/12.1/177/w32/work/installers/windows32\build\pyi.win32\altera_installer_gui\outPYZ1.pyz/subprocess", line 621, in __init__    File "d:/SJ/nightly/12.1/177/w32/work/installers/windows32\build\pyi.win32\altera_installer_gui\outPYZ1.pyz/subprocess", line 830, in _execute_child    WindowsError: [Error 2] The system cannot find the file specified   ----------------------------------------------------------------------------------------------------------  These are the errors. Please somebody help me.It's urgent. Thank you in advance.

Windows has a file name length limit. Try it with the installer in C:\. Also, make sure the install location has a short name with every character A-Z, a-z or 0-9 and no spaces in the name (like "Program Files") I just use C:\altera
