Creative Cloud Desktop does not detect installed en_GB apps after installLanguage changed to ja_JP
I use Windows 11 in Japan, but my Adobe applications were installed in English (International).
The applications are physically installed and launch normally. Adobe's local installation database reports Status=1 and InstallLang=en_GB for the installed applications, including:
- Premiere Pro 24.6.8, 25.6.6, and 26.3
- After Effects 24.6.8, 25.6.6, and 26.3
- Photoshop 27.8
- Illustrator 30.6
However, the current Creative Cloud Desktop preference shows installLanguage=ja_JP. Creative Cloud Desktop displays the existing applications as not installed and offers only an "Install" button.
Adobe Fonts management and synchronization are also malfunctioning. Fonts used in active production projects have appeared as missing.
I have already tried:
- Signing out and back in
- Rebuilding the Adobe User Info credentials
- Rebuilding the Apps Hub cache and preferences
- Creative Cloud Desktop Repair
The problem remains.
Adobe Support suggested resetting all Creative Cloud Desktop data and, as a later option, removing and reinstalling all Adobe applications. A full removal is not acceptable without stronger evidence because this production workstation contains multiple Adobe application versions, many third-party plug-ins, panels, scripts, presets, custom keyboard shortcuts, workspaces, and licensed production tools. Some older application versions may also no longer be downloadable.
My questions are:
1. Can the en_GB / ja_JP mismatch itself cause Creative Cloud Desktop to stop recognizing already installed applications?
2. Is it safe to change only the default install language back to English (International) while leaving all existing applications installed?
3. Could changing that setting trigger an automatic uninstall, reinstall, or modification of existing applications?
4. Is there a supported way to force Creative Cloud Desktop to rebuild or rescan its installed-application inventory without reinstalling the applications or affecting plug-ins and preferences?
5. Should the Adobe Fonts synchronization problem be diagnosed separately from the installed-application detection problem?
I am specifically looking for a non-destructive recovery procedure.
