PRB: Setup Cannot Register Reg_mfc42.dll in the System Registry (165953)
The information in this article applies to:
- Microsoft Visual InterDev 1.0
This article was previously published under Q165953 SYMPTOMS
During the setup and installation of the Microsoft Visual InterDev 1.0
client, the following error message can be encountered:
"Setup cannot register reg_mfc42.dll in the system registry because an
older version is in use. Close all applications and try again."
This error message is referring to the file MFC42.DLL.
CAUSE
This error message can occur even when all applications and tasks are
closed. Programs that modify System files for Windows 95 or Windows NT can
cause MFC42.DLL to load into memory when Windows loads, causing MFC42.DLL
to instantiate before any programs are launched. An example of a program
that does this is Norton Utilities for Windows 95/NT. Even when removed
from starting, MFC42.DLL is still loaded on startup. An aborted setup from
Visual InterDev could also cause this problem.
RESOLUTION
Rename all copies of MFC42.DLL and, if present, MFC42u.DLL and restart
your machine. Once your machine has restarted, you may encounter various
errors from system files that are attempting to load MFC42.DLL. As long as
the Visual InterDev Client Setup is completed successfully, these errors
will cease when the machine is restarted.
