Can you check in the source code, if there are copyright or other special symbols? alternatively, you can change the file encoding for the source files to UTF-8 and then recompile. We'll check here internally if the files are properly converted.
Did you try to run the installer directly using Wine? That's what I tried first, but I couldn't manage that the installer connects to the tms license server to validate, so that didn't work. Mr. Fieren told me that I just have to allow a http connection on port 80, but I couldn't make it work.
I now see at the screenshot, you are compiling the VCL packages, but you only need to compile the TMSFNCCoreWEB.dproj, which is the Visual Studio Code specific WEB package. the other ones do not need to be compiled.
