If you have trouble:
======================

If you have problems running this patch:

- Make sure you copied the appropriate patch files.

- Make sure you have the correct version of the files to be updated.
This patch will only patch files from MSVC v1.00.

- If you receive the warning message "Warning wpt0015: Old File does not
exist" from the patch utility, note the following:

1) Ensure that the current directory contains the files to be updated.

2) The default installation for the Professional Edition does not include
alternate math runtime libraries (SDLLCAW.LIB / MDLLCAW.LIB). If you
did not install these libraries, ignore this message.

- If you receive the warning message "Warning wpt0036: Invalid copy of
file found. No update can be done" from the patch utility, check to make
sure you're using the correct patch files for your edition of Visual C++:

Professional Edition: PROLIB.RTP
Standard Edition: STDLIB.RTP
