DOCUMENT:Q191704 24-AUG-1998 [vbwin] TITLE :PRB: Unable to Load File to Register It During Setup PRODUCT :Microsoft Visual Basic for Windows PROD/VER: OPER/SYS:WINDOWS KEYWORDS: ====================================================================== --------------------------------------------------------------------- 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" 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: 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.
