How to Fix a DLL File on My Computer

1. Download and run DLL-repair software. These programs automatically seek out and replace malfunctioning or missing DLL files, and will delete any unnecessary DLL files that may exist as a result of spyware or malware. You can download programs dedicated to fixing DLL issues free of charge at dll-error.com or CNet.com.
2. Reinstall the corrupt or missing DLL files. If the corrupt DLL files were originally installed during the installation of a particular type of software, copy them from the software source disk and paste them into the directory of the corrupt or missing DLL files. Click 'Yes' or 'Yes to All' when prompted to choose whether you wish to replace existing DLL files.
3. Reinstall Windows. This will return all DLL files to their default status and erase any corrupt DLL files on your system.
