It is not possible to enter materials in the heat exchanger simulation software EDR

Hasn’t everyone encountered such a problem?

EDR (Exchanger Design & Rating) software is a tool used to design and evaluate the performance of heat exchangers, including types such as shell-and-tube, plate, and air-cooled heat exchangers. If you encounter issues with entering materials while using EDR software, you can try the following solutions: 1. **Check the software licensing and configuration**: Ensure that your EDR software has valid licensing, as some functions may not be available due to licensing problems. At the same time, check whether the software is configured correctly, including whether the appropriate working environment and user options have been selected. 2. **Property database issue**: The property database is a key component of EDR software, providing the necessary thermodynamic and physical property data for simulations. If there are issues with the property database, or if it is accidentally deleted or damaged, you need to repair or reinstall it. 3. **Software compatibility**: If your operating system or other software is incompatible with EDR, it may also prevent the entry of materials. Please confirm that your system meets the minimum requirements for the EDR software, and check for any software conflicts. 4. **Updates and Patches**: Check for any available software updates or patches; installing the latest updates can resolve some known errors and issues. 5. **Restart the software or computer**: Sometimes a simple restart of the software or computer can solve the problem, as this will clear temporary data and potential minor errors. 6. **Check user permissions**: If you are working in the web version of EDR, it may be that improper network permissions or user permission settings are preventing you from entering materials. Please contact the system administrator to verify your account permission settings. 7. **Read the software manual or help documents**: Sometimes there may be specific requirements for operating the software; read the manual or help documents carefully and follow the correct steps. 8. **Contact technical support**: If the above methods do not resolve the issue, it is recommended to contact the technical support team of the software provider; they may need you to provide additional information in order to diagnose and fix the problem. Before attempting to resolve the issue, please make sure to back up your work data to prevent loss of data during troubleshooting. .

Thank you. If I need to reinstall the data, how should I do that? The important thing is that ASPEN PLUS works properly; so is it not a problem with the database? My system is WIN11; it can’t be a system issue, right?
