If you try to run the Microsoft Data Access Components setup on a Windows 95 computer, you get a warning indicating that you need DCOM95 to install MDAC.


To install correctly on a Windows 95 computer, MDAC requires that DCOM95 be installed. MDAC installs components that rely on DLLs installed by DCOM95 in order to register correctly. Note that DCOM95 is not required on a Windows NT 4.0. In some cases, DCOM may not be installed on a Windows 98 computer. If it has not been installed, then DCOM98 should be installed prior to the installation of MDAC.


Download and install DCOM95 prior to installing MDAC. You can obtain DCOM95 for Windows 95, version 1.3 from the following Microsoft web location:
DCOM95.exe is also available on the Microsoft Visual Basic 5.0 CD-ROM (Enterprise, Professional, and Standard editions) in the \Pro\Tools\DCOM95 directory.

After downloading and saving DCOM95.exe, double-click DCOM95.exe and proceed through the installation of DCOM95. This process requires you to restart your system upon completion.

If DCOM is not installed on a Windows 98, DCOM98 will need to be installed prior to the installation of MDAC. DCOM98 can be found at the above Web site.


This behavior is by design.
