Sysquake Registration File

Sysquake Pro and Sysquake Application Builder require a registration key file in order to run. Please follow the instructions you have received with Sysquake.

Licenses for multiple computers and site licenses do not require separate registration for each computer; the same registration file is used on each computer. If your company or university has acquired such a license, a single person should be responsible for the registration file deployment; Calerga cannot easily accept and validate requests from multiple persons for the same license.

Where SQ_Reg.key is located

The registration information is stored in the file SQ_Reg.key on the hard disk. Its location depends on the operating system.

Windows

On Windows computers, SQ_Reg.key is located in the same folder as Sysquake.exe, typically in the directory C:\Program Files\Sysquake.

If the installer application finds the file SQ_Reg.key in the same directory where it is located, it copies it automatically to its final location.

macOS

On macOS computers, SQ_Reg.key can be located in three different places:

in the same folder as the Sysquake application;
in ~/Library/Calerga, where ~ stands for your home folder;
in /Library/Calerga (starting in the boot volume).

If Sysquake Pro or Sysquake Application Builder cannot find a valid registration file at startup, it will request one and copy it to ~/Library/Calerga. If Sysquake is used by different users on the same computer, you can move it to /Library/Calerga (you need administrator privileges to do that).

The folder of Sysquake is usually not recommended to reduce clutter in the Applications folder and to avoid deleting it when you replace Sysquake with a newer version.

Linux

On Linux computers, SQ_Reg.key is located in the base directory of Sysquake, typically /usr/local/sysquake.

Remark

The serial number is linked to your name and your company's name. The protection system is designed to permit you to reinstall the serial number easily, on the same or a different computer. You may even copy the registration file onto different computers if you have a multiple license for the same software, or to your private laptop computer. License files for Windows and Mac OS are compatible. Simply make sure you comply with the license terms.

When you perform a minor upgrade of Sysquake, you can keep the same registration file without running the registration application or contacting Calerga again.

What's in the Serial Number

The serial number is not a random string of letters and digits. It can be decoded as follows. A typical serial number looks like

500549a-999999-0a20.a392

To decode it, split it into six parts:

vvvwwwf-yyyymm-ssss.ssss

Each group of characters has the following meaning:

vvv, a group of three digits, is the first version number for which the license is valid; 500 means 5.0.
www, a group of three digits, is the last version number for which the license is valid; 549 means 5.4.9. Note that this is not a commitment to offer free upgrades, or any upgrade at all.
f, a single letter, identifies additional capabilities of Sysquake; a means none. It is not used in current releases.
yyyy, a group of four digits, is the last year of the validity of the license; 9999 means no expiration.
mm, a group of two digits, is the last month for which the license is valid; 99 means no expiration.
ssss.ssss, a group of eight hexadecimal digits, is an encrypted checksum which binds the serial number to other bits of registration information.
