You could easily write a post-setup executable in VFP, and use that to make the files read-only. You'd need to use an API call (SetFileAttributes()) to mark the files read-only. There's an example of using SetFileAttributes() in the FAQ here on UT; the following will set a file to read-only:

DECLARE INTEGER SetFileAttributes IN WIN32API ;
   STRING lpFileName, ;
   INTEGER nAttributeMask

cFileName = 'C:\MyPath\MyFileToBeMadeReadOnly'
IF SetFileAttributes(cFileName,1) = 1
  * it worked
ELSE
  * it didn't
ENDIF

See WINNT.H in Visual C/C++'s INCLUDE files for the full set of values for attribute masks.
