DLL files are important the overall performance of your apps and PC health. Missing DLL files may result in the inability to load certain programs or application you’ve installed on your computer.
There are a few variables to finding and installing your missing DLL files. DllIndex hosts hundreds of thousands of newly updated files, ready for free download within the site. The alternative would be to use an automated solution, software programs like Fortect who fix, or replace damaged and missing DLL files.

There are manual options that won’t cost you anything, for example if you are having trouble loading an application, you can uninstall, then reinstall said application, hoping for a resolution. Writing the support contact of the application requesting the specific DLL file be sent to you is also an option.
Windows offers internal tools as well, such as the SFC (System File Checker). If some Windows functions aren't working or you experience Windows crashes, use the System File Checker to scan Windows and restore your files.
