Total Validator Basic

Total Validator Basic runs on Windows (7-11), macOS (Sierra-Sonoma), and Linux (x64).

To access all the features of Total Validator, such as Document Object Model (DOM) testing for javascripted sites, you should install our browser extensions as well.


You do not need to uninstall the old version, unless you are switching between the Windows .msi and .exe versions. These install into different places, and having both installed at the same time can cause issues.


Windows: To install, run the .msi or .exe file you downloaded. Uninstall from the Windows control panel as normal. If any warning messages appear when you install Total Validator, please read this FAQ. Note that having both the .msi and .exe versions installed at the same time can cause issues, so we recommend only installing one of these.

macOS: To install, open the .dmg file you downloaded and drag the Total Validator icon into your Applications folder, overwriting any existing installation. To uninstall, drag this into the Trash. If any messages appear when you first try to run Total Validator, please read this FAQ.

Linux: To install, copy the .tar.gz file you downloaded into the directory of your choice and run the following command to create the TotalValidatorBasic directory that contains the application:

# tar xvfz TotalValidatorBasic.tar.gz

To uninstall, delete the TotalValidatorBasic directory.
