Verify that the PATH variable used to display or set the search 
path for executable files does not contain quotation marks. If 
it does, remove them. To verify your PATH variable, type 
PATH  in the command prompt of the systems on which you plan 
to install Service Pack 5. Running the service pack installation
may fail with the following message if this is not corrected:

  "Setup initialization could not be successfully completed.
  cfgchar.exe could not be executed. Please check the relevant
  out file"

however, you need to make sure that the directory name does not
contain space characters.
