CurveExpert Basic 2.2.3 documentation

Installation and Activation



To install on Windows platforms, simply run the installer, either from the command line or by double clicking it in the Windows explorer. The automated installer will start and guide you through the installation process; just follow the on-screen prompts. CurveExpert Basic will install for all users (if you are the Administrator), or for you only (if you are not). This allows you to install CurveExpert Basic without any Administrator privileges.

Windows automated installs

The installer for Windows operating systems recognizes two command line switches: /S for silent installs, and /D=dirname to specify where the program should be installed. For example, in an environment where a system administrator would want to install the program silently to the directory “d:\sharedprogs”, one would do:

> CurveExpertBasic-2.0.0-win64.exe /S /D=d:\sharedprogs

Windows automated uninstalls

The uninstaller for Windows operating systems can be used for silent uninstalls. If the software was installed in the directory “c:\sharedprogs”, one would do:

> "c:\sharedprogs\CurveExpert Basic\uninstall" /S

Note that there are no quotes used in the last _? option, even if there are spaces in the path.

Starting a Trial

If you want to evaluate CurveExpert Basic on a trial basis, you can start a trial period by selecting Help->Activate Trial Period; note that an Internet connection is required for the starting of the trial period, but is not required once the trial period has been activated.


If you use a proxy for Internet access, please set the appropriate proxy settings in Edit->Preferences->Advanced (see Proxy settings).

This trial period is active for approximately 30 days from activation date. During this period, all features of CurveExpert Basic are accessible. When the software is out of its trial period (either before or after), most output functions are disabled, and a watermark appears on all graphs.

After Purchase: licensing

If you have purchased a CurveExpert Basic license, you will receive the license information via email. Licenses are fulfilled within 24 hours of receipt; average turnaround time between purchase and license fulfillment is 2 hours.

Proceed to Help->Enter License, and paste the entire email into the box. The fields below the box (Name, Company, etc.) will update, and you can then press OK to complete the process.

If you are not sure how to copy and paste the email, highlight the text of the email with your mouse (click and drag), and press Ctrl+C (Cmd+C on a Macintosh). Then, just press the Paste button in the Help->Enter License window.

Thank you for your support of CurveExpert Basic!

Automated licensing

System administrators may need a means to apply the license via the command line. To do this, save the licensing email as a text file, and then pass the text file to CurveExpert Basic on the command line as follows:

> cebasic.exe --license the_license_filename.txt --quit

Make sure that you are in the same directory as the executable when running this command, so that the executable can find its required shared libraries. This procedure works under both Mac and Linux; under Linux, simply remove the .exe from the commands above. On macOS, you will have to use the “open” command:

> open /Applications/ --args --license the_license_filename.txt --quit

The application will write a file “license.log” that prints the results of the licensing (success or failure).
