- Photoshop now works on Linux via fixed compatibility layers, not official support
- Creative Cloud installers fail due to missing Windows subsystems in standard Linux environments
- Wine struggles with Adobe installers as Internet Explorer behavior remains deeply ingrained
The long-standing incompatibility between Adobe’s Creative Cloud suite and Linux operating systems remains a major obstacle for users transitioning to open source platforms.
Recent developments suggest that this barrier may begin to weaken due to targeted technical work, as a developer known as PhialsBasement has documented a method to install and run recent versions of Photoshop, specifically versions 2021 and 2025, on Linux systems.
This process bypasses the official installation path, which Adobe has limited to Windows and macOS environments.
Decrypt installer requests
The main challenge lies in the complex architecture of the Adobe Creative Cloud installer, which depends on specific Windows subsystems that Linux does not natively provide.
The Wine compatibility layer translates Windows API calls into POSIX-compatible calls, but it has traditionally struggled with these installers. The main failure points were MSHTML and MSXML3.
These components render the installer’s HTML and JavaScript interface and parse its XML configuration files.
The installation framework expects an environment that mimics the older behavior of Internet Explorer, which standard Wine configurations cannot adequately reproduce. The solution introduces a series of fixes that change the way Wine interacts with these subsystems.
To address XML parsing issues, the patches encapsulate data in CDATA sections to avoid strict parsing errors on Linux, and also fix Wine’s internal handling of identifiers so that system calls are routed and executed correctly.
A key part of the fix forces Wine to emulate Internet Explorer 9’s event handling behavior. This allows the installer’s user interface to work as intended by its developers.
According to the developer reports, these changes allow the installation process to complete without errors and the application to run with stable performance.
This advancement allows Linux users to access Photoshop as a powerful image editor. It also suggests that other Adobe applications, including video editing software, could run on Linux in the future.
The developer initially submitted the patches to Valve’s Proton repository, a Wine fork optimized for gaming, but maintainers rejected them and suggested submitting them through WineHQ instead.
Therefore, users who want to apply this method must manually compile a patched version of Wine from the developer’s source code.
Despite the technical prowess, the path taken by these fixes highlights the fragmented nature of compatibility development.
The process requires technical expertise, which limits its practical scope and gives it more symbolic value than immediate widespread use.
This work shows that the barriers blocking professional authoring software on Linux are not insurmountable, and that early adoption of these patches could improve access to other Adobe applications.
For now, Linux users must rely on unofficial patches, since no native support exists.
