SYMPTOMS
========
Under some circumstances, the Visual C++ copyright logo displays the string
"Unauthorized copy of Microsoft Visual C++" where the registered owner's name
belongs. This message may occur when the user manually copies the executable
files from the distribution disks and does not install them with the Setup
program or when virus protection software is running during installation.
MORE INFORMATION
================
When you install 16 bit edition of Visual C++, it modifies the following four
files to reflect the name entered on the registration screen: APSTUDIO.EXE,
MSVC.EXE, MFCAPPWZ.EXE, and MFCCLSWZ.DLL. If these files are not updated, the
"unauthorized copy" message appears. To correct this situation, run Setup and
install the affected component(s). To reinstall only the files the Visual C++
Setup program modifies, select the following from the Installation Options
dialog box:
Microsoft Visual Workbench
Microsoft Foundation Classes
Microsoft App Studio: Resource Editor
NOTE:There is no App Studio in Visual C++ 2.x and 4.x. The files modified in 2.x
are MSVC.EXE and SPYXX.EXE. For 2.x, install components "Microsoft Visual C++
Development Environment" and "Microsoft Foundation Classes". The files modified
in 4.x are MSDEV.EXE, SPYXX.EXE, and MSDEV\BIN\IDE\MSVCCPP.PKG. For 4.x, install
component "Microsoft Developer Studio".
In Visual C++ 5.0 and 6.0, a large number of files will be modified due to
executable binding that occurs during setup. The file that contains the
authorization information is MSDEV.EXE.
For Visual C++ 2.x, 4.x, and 5.0 another solution is to run setup with the /f
switch (for example, "setup /f" without the quotes). It is important that you
run the setup.exe in the Visual C++ subdirectory on the CD. For Visual C++ 4.x
it is in X:\MSDEV where X: is the letter designation of your CDROM drive. For
Visual C++ 5.0, it is in X:\DEVSTUDIO.
The "unauthorized copy" message can also appear when VSAFE or other memory-
resident virus protection software is loaded by AUTOEXEC.BAT. VSAFE is a virus
protection utility included with MS-DOS version 6.0. By default, the utility
detects modifications made to executable files. If VSAFE is loaded and the VSafe
Manager for Windows is running with executable checking enabled, the VSafe
Manager displays a dialog box when Setup attempts to update the executable
files.
If VSAFE is loaded, but the VSafe Manager for Windows is not running, the
computer beeps when Setup attempts to update the executable files and Setup does
not update the files with registration information. When Visual Workbench
starts, the logo screen indicates an unauthorized version.
To resolve this situation, edit your AUTOEXEC.BAT file to comment out or remove
the command that starts VSAFE or the other memory-resident virus protection
software. The Visual C++ README.TXT file recommends against running VSAFE with
Visual C++. The Visual Workbench may appear to hang with VSAFE detects that an
executable file is changing during the linking process. Once you remove VSAFE or
other memory-resident virus protection software, run Setup to reinstall the
affected component(s).
