Installing MCell (Windows)


MCell is included in the CellBlender 1.1 bundle (linux, windows). You only need to install MCell separately if you would like to run it outside of CellBlender or if you are setting up CellBlender from scratch.

Extract MCell

Open the zipped Windows binary through the browser (shown here with Google Chrome).


Windows File Explorer should appear, displaying the MCell binary (mcell.exe) within the zipped file.


Drag and drop the binary to a new folder. For this example, we will create a new folder in the top level C directory called bin (i.e. C:\bin). To create a new directory, right click on the background in File Explorer, select New->Folder, type the name of the folder (e.g. bin), and hit Enter.


Put MCell in a PATH Directory

This step is optional but is highly recommended if you will be running MCell from the command line (i.e. without CellBlender). First, right click on Computer and select Properties.


In the new window, click the Advanced system settings button.


Then click the Environment Variables button in the System Properties window. In the Environment Variables window, select the Path entry in the list of System Variables, and hit the Edit button. At the end of the list of Variable values, add ;C:\bin\. If you extracted MCell into a directory besides "C:\bin\", use that instead. Also, be sure to use the initial semicolon and the trailing backslash.


Test MCell

To run MCell in Windows without CellBlender, we are going to use PowerShell, which is included with Windows 7 and 8. Alternatively, you could use the Command Prompt, but we will not cover that here. To run PowerShell, hit the Windows key, type powershell, and hit Enter (Windows 8 pictured below).


Windows PowerShell will now appear on the screen. Type mcell.exe and hit Enter. If you see the following text on your screen, you have set up your PATH correctly.
