Once you have downloaded ees64pro.exe (approx. 45 MB), follow these steps:
If you cannot afford EES, consider these legal options:
| Software | Type | Cost | Key Differences from EES | |--------------|----------|----------|-------------------------------| | Python with SciPy/SymPy/Cantera | Open-source | Free | Requires coding; no GUI; Cantera provides thermodynamic properties. | | Octave/FreeMat | Open-source | Free | MATLAB-like; no built-in steam tables. | | REFPROP (NIST) | Property database | Free for small use | No equation solver; but pairs with Python. | | OpenModelica | Open-source | Free | Equation-based modeling; steeper learning curve. | | EES Academic (official) | Limited free | Free | Max 50 equations; no parametric table saving. |
| 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 the $1,000+ price tag is prohibitive, consider these legitimate alternatives before resorting to piracy:
| Tool | Cost | Pros | Cons | | :--- | :--- | :--- | :--- | | Python + CoolProp | Free | Powerful, scripting-based, unlimited equations | No GUI, steep learning curve, no built-in plotting GUI | | MATLAB + TToolbox | $$$ (Often Institutional) | Excellent for dynamics/controls | Heavy, slow for thermodynamic cycles | | EES Academic (Yearly) | $99 (Student) | Full professional features for 12 months | Watermarked plots, no commercial use | | GNU Octave | Free | Open source | No thermodynamic property libraries built-in |
Recommendation: If you are a student, buy the Academic license. If you are a professional, the productivity boost of EES Professional pays for itself in one week of work.
Error 1: "Component 'MSCOMCTL.OCX' is missing."

The Engineering Equation Solver (EES) Professional version is a powerful computational tool developed by F-Chart Software. It is specifically designed to solve large systems of coupled non-linear algebraic and differential equations, making it a staple in mechanical engineering fields like thermodynamics and heat transfer. Key Features of the Professional Version
The Professional license offers significant upgrades over the standard version to handle complex engineering tasks:
Variable Capacity: Supports up to 12,000 variables and equations (upgradeable to 24,000 in the 64-bit version). There is no free, permanent full version of
Automation & Scripting: Enables the use of Macros and the creation of Distributable executable files that can run on computers without EES installed.
Advanced UI: Allows for multiple tabs in the Equations window and the inclusion of animation and an AI Librarian.
Property Database: Includes high-accuracy thermodynamic and transport property data for hundreds of substances, eliminating the need for manual table lookups. How to Download and Install
Access to EES is typically restricted to licensed users or students at participating institutions.
Official Source: Downloads are managed through the F-Chart EES Download Page.
Academic Access: If you are a student (e.g., at UW-Madison), you may have access to a specific academic installer like setup_ees_acad.exe. License Activation:
