Windows installation instructions
Although it is not required, before installing Mstat 8.1, you can uninstall (go to 'Add/Remove Programs' in the Control Panel) any earlier versions of the program (remember to copy any data files to a new directory). Download the file "Mstat81-setup.exe" or Mstat81_arm64-setup.exe (see link belows) depending on which processor your computer uses, to a temporary directory. To install Mstat, double-click on the setup file and follow the directions provided by the installer program. Note that this version of Mstat requires a 64-bit version of Windows. If you require a 32-bit version, see the Previous versions page. Installation by someone with Administrator rights will make the program available to all users. Although the program was developed on Windows 11, it will run on Windows version 10 as well. To start the program, choose Mstat 8.1 from your Start menu or double-click the icon on your desktop.

Mstat version 8.1 for Windows arm64 (11.4 M)
Notes: You may receive a "Publisher unknown" warning when you download or run the Mstat81 setup file. Simply click on the More information choice in the dialog and indicate that you wish to keep or run the application. Detailed instructions may be found here.
The arm64 version of the installer will run only on computers using that processor. The Intel version will install and run on arm64 computers but will use an emulation mode that is slower than the native arm64 version.
macOS installation instructions
Mstat 8.1 for macOS requires version 12 (Monterey) or later of the operating system. The application includes universal binaries that will run natively on Apple M1 (and later) and Intel CPUs. For older versions of macOS (back to 10.15, Catalina) see the Previous versions page.
To install the program, download the disk image file to your desktop. The disk image should open automatically (or double click it) and display a license file. Copy the Mstat folder to the Applications folder or your home directory. For convenience you can place the Mstat program in your dock. Be advised that the setting in Security and Privacy under the General tab must allow apps downloaded from both the App Store and identified developers.

The macOS installer is signed and notarized in compliance with the macOS security requirements. The first time you run Mstat, you will see a dialog that asks "Mstat is an app downloaded from the internet. Are you sure you want to open it?" Simply click the Open button to start the program.
Linux installation instructions
Mstat 8.1 requires that the Qt libraries (version 5.12 or later) be installed on your system. The program was tested on Debian 12, Ubuntu 22.04 and 24.04, and Linux Mint 22, but should run on other recent distributions. This version of Mstat requires a 64-bit OS. For a 32-bit version see the Previous versions page. To install the program, download the archive "mstat81.tar.gz" to your home directory and expand it to give the folder "mstat81". To run the program, open a terminal window, and enter "mstat81/mstat" or change to the mstat81 directory and enter "./mstat".
