RESOLUTION

To resolve this problem, replace the missing registry keys. To do this, use one of the following methods.

Method 1: Reset the Registry Keys by Using the Mdac.inf File

Use Mdac.inf to reset the registry keys.

Note This program may prompt you for your Windows CD to obtain new files.

Do one of the following as appropriate for your operating system and if you have the Windows CD.

For the Retail Editions of Microsoft Windows 2000 and Microsoft Windows XP

1. Click Start, and then click Run.
2. In the Open box, type path\inf, where path is the path of your Windows folder, and then click OK.
   
   For example, type C:\Windows\Inf or C:\Winnt\Inf. By default, C:\Windows is the folder where Windows XP is installed. By default, C:\Winnt is the folder where Windows 2000 is installed and the folder where Windows XP is installed if you upgraded Windows 2000 to Windows XP.
3. On the Tools menu, click Folder Options.
4. On the View tab, in the Advanced Settings box, click Show hidden files and folders, and then click OK.
5. Right-click Mdac.inf, and then click Install.
6. If you are prompted for your Windows CD, insert the Windows CD in the CD-ROM drive or DVD-ROM drive.
7. Click the I386 folder on your hard disk (typically, C:\I386), and then click OK.
   
   Note: If the I386 folder is a subfolder of the Windows folder, on some computers, you cannot select it. In this case, type the full path in the Copy files from box (for example, type C:\Windows\I386 or C:\Winnt\I386), and then click OK.
8. Restart the computer.
