Try this and if it's wrong maybe you could put a little effort into asking for help. Like explaining the whole problem...

What ever the newer ,DLL file is named is what you put there.....
You have obviously gotten a newer version of that particular .DLL so you just copy the newer version...

Copy..... Paste into directory and your done, no need to type all that into the command prompt, when you can just use Explorer....

As you don't state your OS I am guessing that it is Win2000 or XP (WINNT)

I do not see how what you are attempting will work. In your first command line you are renaming a file. In the second, you seem to be trying to overwrite/replace it using its old name?

.:front2back:. is spot on...................just use Windows Explorer................just rename the old file and drag and drop the new one.

Depending on how you got the new file, you may need to create a folder and unzip/decompress it first.

EDIT: Here is a good source of .dlls complete with tutorial ;)

WINNT\System32 is the footprint of Windows2000. WINNT is used and there is a system32 dir.

There is one mystery solved, however, I still can't figure out why the hell he is using an XCOPY command line switch with the COPY command. The /r switch is not part of the command line syntax for the COPY command.

F2B is right. Use explorer because you sure as hell aren't going to get anywhere using bad syntax on the command line.

Code:

C:\WINDOWS\system32>copy /?
Copies one or more files to another location.

COPY [/D] [/V] [/N] [/Y | /-Y] [/Z] [/A | /B ] source [
    [+ source [/A | /B] [+ ...]] [destination [/A | /B

  source      Specifies the file or files to be copied
  /A          Indicates an ASCII text file.
  /B          Indicates a binary file.
  /D          Allow the destination file to be created
  destination  Specifies the directory and/or filename
  /V          Verifies that new files are written corr
  /N          Uses short filename, if available, when
              non-8dot3 name.
  /Y          Suppresses prompting to confirm you want
              existing destination file.
  /-Y          Causes prompting to confirm you want to
              existing destination file.
  /Z          Copies networked files in restartable mo

The switch /Y may be preset in the COPYCMD environment
This may be overridden with /-Y on the command line.  D
to prompt on overwrites unless COPY command is being ex
within a batch script.

To append files, specify a single file for destination,
for source (using wildcards or file1+file2+file3 format

Hmmmm, no R switch for COPY.

Interesting. There is an R switch with XCOPY.

I hear McDonalds is hiring. LOL.
