ALTERA CORPORATION ALTERA SOFTWARE INSTALLATION AND LICENSING ■ 86
A: If you purchase a subscription license for the Quartus II or MAX+PLUS II
software, the license file that you receive from Altera is valid for the current
version and earlier of the Quartus II or MAX+PLUS II software when you
purchase the software, for up to one year from the date of purchase.
You can find version information in your license.dat file. Figure 1 shows a
FEATURE line from a sample license.dat file:
Figure 1. Quartus II Software Feature Line Example
The 2009.12 in the license file in Figure 1 is the version information for the
Quartus II software. In this license file example, any version of the software
released up to and including September 2009 is enabled. Additionally, the
inclusion of permanent in the FEATURE line indicates that the license file
never expires or stops working for enabled versions of the Quartus II
software.
You can check the version of the Quartus II software by clicking About
Quartus II on the Help menu. The software version is at the top of the About
Quartus II dialog box.
You can check the version of the MAX+PLUS II software by clicking About
MAX+PLUS II on the Help menu. The software version is in parentheses at
the top of the About MAX+PLUS II dialog box.
Q: I just upgraded to the latest version of the Quartus II software. Now my
Altera software says the license is not valid, but I know I have purchased an
Altera software subscription. What should I do?
A: To direct the Quartus II software to check the Altera website for license
file updates, on the Tools menu, click License Setup. In the License Setup
page, click Web License Update. If an updated license file exists, the
Quartus II software automatically downloads and installs the correct
license.
