How to register a DLL file in Windows
In the run, enter the Regsvr32dllname.dll command, where dllname is your DLL filename.

Right-click the application and select Quick View command on the shortcut menu to see the result information in the "Introduction table" column of the Quick View window that appears later.
How do I know which applications the DLL files are used in?
Run regedit, enter the HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows Currentversionshareddlls subkey to view, and its right window displays all DLL files and their associated data. A number in parentheses to the right of the data indicates that this DLL file is used by several programs. For example: (2) means to be used by two programs, (0) means no program to use, you can delete it.
How do I troubleshoot DLL file loss?
Sometimes when you uninstall a file, you are reminded that deleting a DLL file may affect other applications that use this DLL file. If you know the name when you lose the DLL, you can locate the DLL file in the Sysbakup (System files backup folder) and copy it to the system folder.
If you do not know, when the computer starts and always appear "***dll file Lost ..." Prompt box, you can run in the start/Run Msconfig, enter the System Configuration Utility dialog box, then click the "system.in" tab to find the missing DLL file, and leave it unchecked so that no error is prompted on the boot.
