Once upon a time in the high-stakes world of thermodynamic research, an engineer named Sarah faced a daunting challenge. Her mission: install REFPROP 9.1 , the legendary software from used to calculate the properties of industrially vital fluids. The Quest for the Installer Sarah’s journey began with a search for the sacred installation files. Unlike modern apps, REFPROP 9.1 often arrived on a physical CD-ROM. She inserted the disc and carefully ran the installer, watching as it carved out its home in C:\Program Files\REFPROP . For those without the full version, a "mini" version was sometimes used as a starter. The Excel Trial The real test came when Sarah tried to link REFPROP to Excel. She knew this was no simple task—it required the precision of a master builder. The Add-In: She located the REFPROP.xlam REFPRP91.XLA ) file and meticulously moved it to a trusted folder, avoiding the treacherous default path that Excel often rejected. The Connection: Through the Excel menu, she browsed to her folder and enabled the link, ensuring the "Refprp91" box was checked. The Proof: She typed a magic formula: =Density("water","TP","SI",300,1) . When the cell returned a perfect value instead of an error, she knew the bond was sealed. The Shadow of the Past Later, Sarah faced a "ghost" from her installation. When she eventually upgraded to Version 10 , the old Version 9.1 wouldn't leave quietly. To banish it, she had to perform a ritualistic "clean uninstall," hunting down hidden folders in and deleting lingering files from her system path. me4293 download and setup mini refprop for students 24-Sept-2020 —

Installing and enabling features for REFPROP 9.1 usually refers to setting up its integration wrappers (like the Excel Add-in) or ensuring the DLL and fluid files are correctly linked. How to Install the REFPROP 9.1 Excel Add-in If you are looking to enable the REFPROP features within Excel, follow these steps provided by the NIST REFPROP-wrappers GitHub : Locate the Add-in File : Find the REFPRP91.XLA file, typically located in your main REFPROP installation folder (e.g., C:\Program Files (x86)\REFPROP ). Open Excel Settings : Go to the Developer tab and click on Excel Add-ins . Browse and Select : Click Browse , navigate to your REFPROP folder, select REFPRP91.XLA , and click Open . Enable : Ensure the box for Refprp91 is checked in the list and click OK . Verify VBA : To ensure functions work, open the Visual Basic editor (Alt + F11) and verify that Refprop91Code appears under your modules. Troubleshooting Common Setup Issues Missing DLLs : If the functions return errors, ensure REFPROP.DLL is in your system path or the same directory as your application. Fluid Path : REFPROP must be able to find its fluid and mixture files at runtime. For cross-platform or complex setups, CoolProp can be used as an interface to help REFPROP locate these files more reliably. Legacy Version : Note that version 9.1 is an older release. Official support and the latest fluid models are found in Version 10.0 , which is available through the NIST Standard Reference Database . Are you trying to install REFPROP for a specific environment like Python , MATLAB , or C++ ?

Installation Guide for REFPROP 91 Overview REFPROP (Reference Fluid Thermodynamic and Transport Properties) is an industry-standard software developed by the National Institute of Standards and Technology (NIST). Version 9.1 is a legacy release that provides accurate thermophysical property data for a wide range of fluids and mixtures. Because Version 9.1 is older than the current Windows operating systems, the installation process requires specific attention to file directories and administrative privileges to function correctly. System Requirements and Prerequisites Before beginning the installation, ensure your system meets the basic requirements for this legacy software: refprop 91 install

Operating System: Windows 7, 8, 10, or 11 (may require compatibility settings on newer OS). Disk Space: Approximately 150 MB of free space. Privileges: You must be logged in as an Administrator to install the software.

Step-by-Step Installation Procedure

Locate the Installer: Navigate to the directory containing your REFPROP 91 installation files. This is typically provided as a downloadable executable (e.g., REFPROP91.exe ) or an ISO file. If you have an ISO, mount it to a virtual drive to access the setup file. Installing NIST REFPROP 9

Run as Administrator: Right-click the setup executable and select "Run as administrator." This is crucial; failing to do so may result in the software being unable to write necessary files to the system directories.

User Account Control (UAC): If prompted by Windows User Account Control, click "Yes" to allow the program to make changes to your device.

Installation Directory: The installer will prompt you to choose a destination folder. Linking REFPROP with Other Applications Once upon a

Default Path: By default, the installer often suggests C:\Program Files (x86)\REFPROP . This is the recommended location. Important Note for Legacy Users: If you are updating from a previous version (like 8.0), the path might default to C:\REFPROP . It is generally safer to install 9.1 in the Program Files directory to avoid file permission conflicts, though advanced users may prefer a root directory for easier access to fluid files.

Completing the Setup: Follow the remaining on-screen prompts to finalize the installation. Once complete, you may launch the program. On Windows 10 or 11, if the program fails to launch or crashes immediately, right-click the REFPROP shortcut, select Properties , navigate to the Compatibility tab, and check "Run this program in compatibility mode for Windows 7."
