I think you should find string TYPES.OBJ in all files in your project, after you need remove this string from found files. Before this do not forget to make a backup project directory.
I had a similar problem when I convert old project from BCB5 to BCB 6. When I deleted the string with “.obj” filename from project file with “.bpr” extension my problem was solved.
String in Project1.bpr project file was like:
<OBJFILES value="Unit1.obj Types.obj"/>
after modification:
<OBJFILES value="Unit1.obj"/>
