This might work, if not reinstall again and make sure you do it.
NB: if it's a cracked ISO there should be instructions in an NFO file.
How do I know? I have friends who have got themselves in similar situations with other cracked stuff, I am an experienced trouble shooter from way back before Delta Force, it all started with WAREZ
OK...ready?
Run setup.bat 1st then
Regsetup.exe again. (The batch file runs it but just to be sure, do it again)
If no setup.bat make the batch file yourself:
Backup the game first then as follows.
make a text file called <anything>.txt then rename to .bat and insert the following text, save it
in the DFBHD-TS folder then click and run the file.
@echo off
startw unpack.exe
startw inject.exe "localres.pff"
startw regsetup.exe
del unpack.exe > nul
del inject.exe > nul
del startw.exe > nul
