Purchasing
Installing the software implies that you have agreed the license agreement, which can be downloaded by clicking download the DEA SolverPRO™ license agreement.
Support
Technical Support is by email only; No Telephone calls, No emergency requests
Due to the complexity of technical support issues arising from the many versions of Windows and Excel used in different countries, technical problems may not always be resolved as quickly as some customers may wish. Therefore, we recommend that potential customers make inquiries well in advance of any critical deadlines—such as research paper submissions, conference presentations, or other time-sensitive situations—for which we are unable to provide special accommodations.
While we make every effort to resolve technical issues as promptly as possible, we cannot guarantee timely resolution or support, including assistance with installation problems. We appreciate your understanding of these limitations when making an inquiry.
If an unclear error occurs while running the program, please send us a screenshot of the error message along with your data file (with all confidential information removed), and we will do our best to resolve the issue.
Caveats for Technical Support
Note that requesting technical support is processed only by email. Always include your name, organization, the date you purchased the license and the version number in your correspondence. Also include the name of the person who actually purchased the program before, if it is not yourself. Please be aware that it may take more than a day to resolve any technical issues including Excel setup. Although we try to process the customer requests as quickly as possible, we can not guarantee any turn-around time for answering technical questions.
Relicensing Software because of OS Changes and Hardware Crashes
In the event of a hard disk crash or a Windows OS upgrade after installation, you may need a new registration key. We will issue one free replacement registration key per user only for the latest Version 16, provided that you submit a formal request letter containing the original license information—including the purchase date, version number, user name, and organization—signed by an authorized person other than the licensee.
If you are using a version older than v16, you may need to upgrade it to the latest floating license with a version-up fee. If you are interested, please send us an inquiry.
