And which Rebex DLLs does it reference? Would it be possible to open the project file using Notepad and copy&pasting the relevant section with these references? From the error message, it looks like it's referencing DLLs in c:\Program Files (x86)\Rebex Components R6.9\bin\net-7.0" folder instead of "c:\Program Files (x86)\Rebex Components R6.9\bin\net-4.6".
