To download and install the Professional version of Engineering Equation Solver (EES), you must go through the official developer, F-Chart Software. Because EES is commercial software, a direct "public" download of the Professional version without a purchase or institutionally provided license is not officially available. Download and Installation Process
Obtain the Setup File: You can download the latest version of the EES setup executable (.exe) directly from the F-Chart Software website.
Acquire the License File: The Professional version requires a specific license file (typically with a .dft extension). This is provided to you by F-Chart Software upon purchase.
Note: If you are a student, check with your university’s IT department; many institutions provide the license file to their students for free.
Run the Installer: Execute the setup file and follow the prompts. By default, EES installs to a folder named EES32 (for the 32-bit version).
Activate Professional Features: Copy your .dft license file into the same directory where the EES application is installed. When you launch the program (ees.exe), it will automatically detect the license and enable Professional features. Key Features of the Professional Version
The Professional version offers several advanced capabilities not found in the standard version:
Equations Window Tabs: Allows you to organize complex projects into multiple tabs.
External Integration: Can be linked with and controlled by other software like MATLAB, Excel, Fortran, and Python.
Advanced Troubleshooting: Access to the Mastering EES guide directly through the help menu for in-depth tutorials.
Built-in Libraries: Extensive transport and thermodynamic property databases for hundreds of substances, which are essential for fluid mechanics and heat transfer modeling. Helpful Resources

The Engineering Equation Solver (EES) Professional version is a commercial software developed by F-Chart Software. Because it is a licensed product, there is no official "free" download for the full Professional version; it requires a valid license and a specific setup file provided by the manufacturer or your institution. Official Download Channels download ees engineering equation solver professional
If you have already purchased a license or your institution provides one, use these official methods to download the software:
Existing License Holders: If you have a current Instant Update and Technical Support (IUTS) subscription, you can download the latest installer from the F-Chart Downloads page. 32-bit Professional: Accessible via your license number.
64-bit Professional: Requires a separate 64-bit license file (EES.DFT64) and can be downloaded using EES64_XXXX (where XXXX is your license number) as the login.
Academic Users: Students and faculty at participating universities (e.g., University of Wisconsin or University of Alabama) can often download the software through their college's IT portal or via VPN.
Demo Version: A free EES Demo is available for 30 days. It is limited to 50 equations and disables saving/printing. Installation Requirements
To fully activate EES, you typically need two distinct files:
Installer: An executable (e.g., setup_ees.exe or setup_ees_acad.exe).
License File: A specific .DFT file (e.g., EES.DFT) that must be placed in the installation directory (usually C:\EES32) after running the setup. EES: Engineering Equation Solver
The Engineering Equation Solver (EES) Professional version is a high-performance numerical equation-solving program developed by F-Chart Software. It is specifically designed to solve large systems of coupled linear and non-linear algebraic and differential equations. Professional Version Key Features
The Professional version provides significant enhancements over the Commercial and Student editions:
Capacity: Supports up to 12,000 simultaneous variables and equations (upgradeable to 24,000 in the 64-bit version).
Organization: Includes a tabbed Equations window, allowing multiple problems or sub-sections of a large program to be saved in a single EES file. To download and install the Professional version of
Performance: The 64-bit Professional version offers calculation speeds up to double those of the 32-bit version for complex problems.
Advanced Tools: Features include optimization, uncertainty analysis, and high-quality plotting that rivals standalone software. Download and Installation
EES Professional is not available as a free download; it requires a valid license from F-Chart Software or a participating academic institution.
Downloading and installing EES (Engineering Equation Solver) Professional is a two-part process that requires a paid license from F-Chart Software. Unlike standard software, you cannot simply download the Professional executable without first having a valid license file (.dft). How to Download EES Professional
Purchase or Verify License: To get the Professional version, you must purchase a license (typically $1,200 for a single user) directly from F-Chart Software.
Access the Setup File: Once purchased, F-Chart provides a link to download the setup executable (SETUP_EES.exe).
Existing Users: If your technical support (IUTS) is current, you can download the latest installer by logging into the F-Chart site using your license number (e.g., EES64_XXXX).
Obtain the License File: You will receive a unique license file with a .dft extension (e.g., EES.dft) via email.
Installation: Run the .exe installer first, then manually copy the .dft license file into the folder where EES was installed (usually C:\EES32). Key Professional Features
The Professional license is the most powerful tier, specifically designed for complex energy system modeling and high-level engineering tasks.
Equation Capacity: Solves up to 12,000 variables (upgradable to 24,000 in the 64-bit version), compared to just 6,000 in the Commercial version.
"Make Distributable": Allows you to create standalone executable programs from your EES files that can be shared with and run by people who do not own EES. Important note: I cannot provide direct download links
Macros and Automation: Supports the creation and execution of Macros to automate repetitive tasks and external interfacing.
Advanced Plotting: Includes a Plot Thumbnails window for easier navigation and the ability to generate plots using text commands in the Equations window.
Component Library: Provides access to high-level energy system models (e.g., cooling towers, heat exchangers) not available in basic versions.
Python Integration: Directly interface your engineering models with Python scripts for advanced data processing.

I understand you're looking for information about downloading EES (Engineering Equation Solver) Professional and useful reviews. However, I need to provide some important guidance:
If your budget or platform restricts you, consider these alternatives:
| Software | Pros | Cons vs. EES | | :--- | :--- | :--- | | Python + CoolProp | Free, open-source, excellent fluid properties | Requires coding; no GUI | | MATLAB + PDE Toolbox | Powerful, great for dynamics | Expensive; steeper learning curve | | Mathcad Prime | Natural equation notation | Weak non-linear solver | | OpenModelica | Free, acausal modeling | Documentation less polished |
For most thermo-fluids engineers, however, EES remains the fastest path from equation to solution.
| Feature | EES Standard (Student) | EES Professional | | :--- | :--- | :--- | | Equation Limit | 600 equations | 6000+ equations (unlimited) | | Array Size | 300 elements | Unlimited | | Property Libraries | Full access | Full access + external calls | | Runtime Distribution | Not allowed | Allowed (create standalone apps) | | Tech Support | Limited | Priority |
The Professional version is designed for practicing engineers, consultants, and researchers who need to solve large-scale problems and deploy solutions to colleagues without EES installed.
If you are a consultant, use File > Generate Executable. Create a .exe that any client can run (without EES installed) to test your engineering model. This is worth the Professional price alone.
Legitimate sources:
Important note: I cannot provide direct download links or help with cracked/pirated versions, as that would violate copyright laws and potentially expose you to malware risks.
There is no “free lunch” when it comes to professional engineering software. However, legitimate access is more affordable and safer than you might think. Follow these official channels.
