How to Install Missing Dll

1. Insert the original installation CD for the program that has stopped working. Locate the missing .DLL file and copy it to the Windows desktop. If you are unable to find the file, type its name into an Internet search engine. The results will include several websites that host .DLL files for downloading. Download the file and save it to your desktop.
2. Double-click on the 'My Computer' icon, then double click 'C:,' 'Windows' and 'System32.' Depending on your security settings, you may need to click through warnings in order to view the contents of these folders.
3. Drag the .DLL file from the desktop to the System32 folder.
4. Hit the 'Windows' and 'R' keys on the keyboard simultaneously to bring up the 'Run' dialog box.
5. Type 'cmd' in the 'Run' box and hit 'Enter.' This will bring up the Windows command prompt.
6. Type 'regsvr32 (filename).dll', using the name of the file that you are installing, into the command prompt. Hit 'Enter.' You should receive a message indicating that the .DLL file has been successfully registered.
