SYMPTOMS

After you install Microsoft Data Access Components (MDAC) 2.5 on a Microsoft Windows 95/98 or Microsoft Windows NT 4.0 computer, a Windows Setup dialog box appears after every restart, indicating that the MDAC components are being configured.

On Windows 95 computers, the wallpaper may also be removed.

RESOLUTION

This dialog box is harmless, but misleading, because the MDAC components completed their configuration after the first restart, and there is no further configuration to be done.

Steps to prevent this dialog box from appearing:

  1. Start Registry Editor (Regedt32.exe).
  2. Locate the entry named mdac_runonce under the following key in the registry:
    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
    The value of this entry should be similar to the following:
    C:\\WINDOWS\\SYSTEM\\runonce.exe
  3. Click the mdac_runonce entry to highlight it. From the Edit menu, click Delete, and then click Yes if you are prompted to confirm the deletion.
  4. Quit Registry Editor.
If you are redistributing MDAC 2.5 with a software installation package, a supported fix is available that removes this value from the registry. To obtain a copy of this fix, contact Microsoft Product Support Service.

   Date      Size           File name    
   -------------------------------------
   5/12/00   4096 bytes     Rem_dlg.inf
This fix can be distributed with software installation packages that require the installation of MDAC 2.5, and can be used by automated installer software to remove the registry key. It is recommended that you perform at least one restart before you execute the Rem_dlg.inf file.

This fix is included in MDAC 2.6.
