Spend a little time with Mac OS X, you’ll find that you’re completely up to speed before you know it, and more productive than ever. Enjoy Getting started with Mac OS X version 10.7. Try the practice exercises, explore on your own, but most of all, have fun. That’s what using a Mac is all about. Using Mplus for Structural Equation Modeling: A Researcher's Guide - Kindle edition by E. Kevin Kelloway. Download it once and read it on your Kindle device, PC, phones or tablets.

Note: Version 7.31 is not available for Windows XP/ME/Vista, Mac OS X 10.6 Snow Leopard, Mac OS X 10.7 Lion and 32-bit Linux operating systems.
Mplus Version 7.31 is available for 32-bit and 64-bit Windows, 64-bit Mac OS X and 64-bit Linux operating systems.
Memory requirements for Mplus (both RAM and virtual memory) depend on the type of analysis and the amount of data. For example, analyses using numerical integration with large samples can be computationally heavy and may require a large amount of memory.
Mplus 32-bit on 32-bit Windows: The Windows 32-bit operating system limits all applications to a maximum of 2GB of total memory (RAM and virtual memory).
Starting with Mplus Version 4.21, Mplus is capable of using an additional 1 GB of total memory, for a maximum of 3 GB, on some Windows 32-bit operating systems. For Mplus to use the additional memory, the /3GB switch must be specified in Boot.ini. This switch allows applications like Mplus, that are 'large address aware', to use 1 GB of additional total memory above 2 GB.
Note that changes to the Boot.ini may have undesirable effects. Caution should be taken when making any changes. Muthen & Muthen is not responsible for any problems that may arise if such changes are attempted and does not provide support for any problems related to these changes.
Mplus 32-bit on 64-bit Windows: The Windows 64-bit operating system limits all 32-bit applications to a maximum of 2GB (or 4GB for applications like Mplus that are 'large address aware') of total memory (RAM and virtual memory). Note that the /3GB switch is not applicable to Windows 64-bit operating systems.
Mplus on 64-bit Windows: The Windows 64-bit operating system limits all 64-bit applications to a maximum of 8 terabytes (8000GB) of total memory (RAM and virtual memory).
Mplus on Mac OS X: Starting with Version 6.11, Mplus is available on Mac OS X. Mplus Version 7.1 for Mac OS X is available with an Mplus Editor. For previous versions of Mplus, some users have reported successinstalling Mplus on Intel-powered Mac using either Parallels Desktop or VMware Fusion software. Mplus support will not be provided for the installation and use of these software or the installation of Mplus using these software.
Mplus on Linux: Starting with Version 6.11, Mplus is available on theLinux operating systems from the command line. The Linux distributionsthat have been tested are Ubuntu, RedHat, Fedora, Debian, and Gentoo. Mplus forLinux does not run on the Sun Solaris operating system. Themultiprocessing feature in Mplus for Linux is the standardmultiprocessing feature available in Mplus for Windows. The Linuxversion does not currently have special cluster computing capabilities.
For previous versions of Mplus, some users have reported success usingMplus on Linux operating systems with the use of Wine. There was aproblem running Version 5.2 with Wine, but the problem seems to beresolved starting with Version 6.1.
The PATH Environment Variable
The Run Mplus option in the Mplus Editor requires that the Mplus installation directory be listed in the PATH environment variable. The PATH environment variable must also be set at the system level for Mplus to work properly in a multiple user environment. The Mplus installation process will try to set the PATH environment variable at the system level.
If this attempt fails, problems may arise when using the Run Mplus option in the Mplus Editor or when trying to update Mplus. Users will be alerted that Mplus is unable to start when running Mplus or Mplus is not found when updating Mplus.
To fix this problem, the PATH environment variable can be set manually.
Instructions for Windows 7:
Log on with an administrator account.
Right-click on Computer and select Properties.
Click on Advanced system settings and click on the Enviroment Variables button.
The system level variables are located in the bottom section.Locate the Path variable and click on Edit.
Add the Mplus installation directory (default is C:Program FilesMplus)to the end of the Value field, separated from the other directories by a semicolon.
Click OK to exit.
Mplus Temporary Files
Mplus uses intermediate files for controlling outputs. These files are created in the working directory. The working directory is usually the directory with the input file. There is one instance when it is not and that is when Mplus is first opened and the recent file list is used to open a previous input file. To ensure that the working directory is always the directory with the input file, always use the File -> Open/Save options for opening/saving an input file.
There is one other temporary file that is created by Mplus but not stored in the working directory. This file does not contain any specific results from the current run. The only information written to the file is the name of the output file. Mplus stores this file in the directory specified by the TEMP environment variable -- a setting on most computers with the Windows operating system. There is no specific setting in Mplus to change the location of this directory. To change the location where Mplus stores this file, the TEMP environment variable must be changed. This will affect other programs that use the TEMP environment variable.
Instructions for Mplus Silent Installation for Windows
In order to perform a silent installation, the installer must be run once to get the response file used. The installer file must be started via the command line using the following instructions.
Open a Command Prompt with Administrative privileges.
Assuming that the installer file is named ComboWindows64.msi, run the initial installation to get the response file with the following options:
ComboWindows64.msi /lr mplus.iss
Note: The “/lr” is the lowercase letter L and R (with no space after the / or between the 2 letters). Mplus.iss is the name of the response file.
Verify that the installation is complete.
Uninstall Mplus and run the following to proceed with the silent installation:
ComboWindows64.msi /quiet /lu mplus.iss
Note: The “/lu” is the lowercase L and U (with no space after the / or between the 2 letters).
