Unlike some modern apps that detect your system language automatically, Pro100 typically relies on the language files (.lng) located within its installation directory. The software is designed to be lightweight, meaning it doesn't always have a "one-click" flag icon in the main toolbar. Instead, the change usually happens through the configuration settings or by swapping library files. Method 1: Changing Language via the Program Options
If your desired language does not appear in the options, you may be missing the specific language file. Pro100 uses files with the .lng extension to translate the interface.
If you change the language but some elements remain in the previous language, it is likely because your Library or Catalog names are hardcoded. Pro100 organizes furniture, materials, and elements in folders. If these folders were created in a Polish version (e.g., "Szafki" instead of "Cabinets"), the program will continue to display those folder names regardless of the interface language. To fix this, you will need to manually rename your library folders or download an English-specific library pack. Pro100 Change Language

Go to the folder where Pro100 is installed (usually C:\Program Files\PRO100). Find a file named PRO100.ini and open it with Notepad. Method 1: Changing Language via the Program Options
Look for a section header that says [General] or [Interface]. Find the line that starts with Language=.
If it is missing, you may need to download the language pack from the official distributor or copy it from a different installation.
