Endless OS is a Linux-based operating system, which means that it does not have direct support for apps built for other platforms such as Microsoft Windows. However, Endless OS does include an apps ecosystem which provides suitable replacments for many common apps.
If you have a favourite app from another platform that is not available on Endless, feel free to reach out on our Community Forums for suggestions as to which app may be a suitable alternative.
Several office suite options are available on Endless OS:
Adobe PhotoShop is not available, however alternative image editors such as the GIMP GNU Image Manipulation Program are available free of charge in the App Center.
Adobe Illustrator is not available, but you may find Inkscape to be a suitable alternative, also available in the App Center.
If you have an inflexible requirement to run a specific Windows app, you could explore running Windows within Endless OS virtualised in Boxes (available in the App Center), or by dual-Booting Windows and Endless.
