PRB: Unable to Load File to Register It During Setup

ID: Q191704

The information in this article applies to:

Microsoft Visual Basic Professional and Enterprise Editions for Windows, version 6.0
on the following platforms: Win95, Win98

SYMPTOMS

After creating distribution files using the Package and Deployment Wizard (PDW) and then attempting to install the application on a Windows 95/98 computer, you may receive the following error:

Unable to load file "msdadc.dll" to register it

Alternatively, you may see the error:

DLL registration failed

CAUSE

Installation of Microsoft Data Access Components (MDAC) requires installation of DCOM. Setup programs created with the Package and Deployment Wizard use the MDAC installer program, Mdac_typ.exe, to install the Microsoft Data Access Components, which include OLE DB, ADO, and Jet. Mdac_typ.exe requires that the target machine have DCOM installed on it.

RESOLUTION

To fix this problem, install DCOM on the target machine. Either DCOM95 or DCOM98 can be used. The latest version of DCOM95 can be found at the following Web address:

Microsoft COM at http://www.microsoft.com/com

Alternatively, DCOM98 can be installed by running DCOM98.exe found in the DCOM98 folder on the Visual Basic 6.0 CD-ROM, Disk 1. Please note that DCOM98 can install DCOM on both Windows 95 and Windows 98 machines.

STATUS

This behavior is by design.
