Hi there,
is there any way in CbB to change the language?

not yet

Regedit
[HKEY_LOCAL_MACHINE\SOFTWARE\Cakewalk Music Software]
"Language"="English"
 
set it to what is supported by CBL

sry for hacking this, should be changed with UI sometimes i guess or bl-assistant

That will force English. Another way is use the old Cakewalk Command Center. At the time of the OP, English was the only language available. Pretty sure the OP was looking for something else. CbB added multi-language support a week ago with 24.04.1.28. The update automatically sets the language based on the OS.

well, for me it wasn't english after update.inc and i was looking it in Preferences and config files for an hour. So the simplest way is change it with registry, since command center can be unavailable for new users - it's the only way.
