How to Restore a Lost DLL File From Microsoft XP Professional

1. Write the specific file name down when Windows detects the missing or corrupt file. This will appear in a dialog box.
2. Scan your system with the System File Checker (SFC) utility, which is built into XP Professional. It will search for the damaged DLL files and replace them with the original versions. (If the SFC cannot locate the files, it will prompt you to insert the Windows installation CD.) Click Start, then select Run from the menu options. When the command prompt appears, type in 'SFC /SCANNOW.'
This scan could take 30 minutes or longer. When the scan is complete, reboot your computer. You have solved the problem if the error message is gone. If it is still there, proceed to the next step.
3. Download the missing DLL file from the resource webpage link. Search the webpage for the exact DLL file that is missing from your system, and click on the link to download the file to the Windows desktop. Use an unzip utility program to extract the DLL file and readme text. You will find several free unzip utilities on the Internet; refer to your particular program's documentation on how to extract ZIP files.
4. Open the readme text file after extracting the files to your desktop by double clicking on it. The readme file will show you where you will need to move the DLL file in order for it to work properly. Click on the 'Start' botton and choose 'My Computer' to open up Windows Explorer. Click on 'Local Drive C:' to access your computer system files.
5. Locate the appropriate system folder in your computer's hard drive that will contain the DLL file (refer to the readme file for the correct file path). Once you have found the correct file folder, click and hold the left mouse button over the new DLL file on your desktop, and drag and release the file into the proper system folder using the mouse.
