In some cities it is legal for a person to make a copy of a her/his personal original CDs and DVDs if the copies are for her/his own use; in cities where this is so, people may use a NO-CD-crack to their original fallout tactics CDs or DVD (I know how this could have been done in one occasion).
Hypothetically: if the NO-CD-crack does not result in success when used the way it's instruction says, it can be solved by moving the BOS file from the Fallout Tactics folder to the desktop, and moving the NO-CD-crack to the desktop - then running the NO-CD-crack - and then moving the cracked BOS file back to the Fallout Tactics folder from which it was taken. This tip also have good use in Windows Vista, when needed.
If that resulted in success, Fallout Tactics should now work successfully.
PS. there is a hi-resolution patch/mod for Fallout Tactics available online.
