If someone is actively working in a certain language version of Advance Steel (eg German) and runs another language version in parallel (eg USA), the German version will take over the complete settings of the Management tools from the USA version including the language. This can be only eliminated by restarting Advance Steel - super task with dozens of open models and drawings.
C: \ Program Files \ Autodesk \ AutoCAD xxxx \ ADVS \ ManagementTools.exe
Please disable to get another language version of Management Tools in the active instance of Advance Steel by default (disable to read another INI language data for non-compatible version in C:\ProgramData\Autodesk\Advance Steel xxx\xxx\Management Tools, ....)
