One method to register DLL files on your computer is via manual registration. Manually registering a DLL file is quite simple and can be done in only a few steps.
In Windows click on Start and then click on Run.
Input in the Run field cmd. From the Programs list right click on cmd.exe and select Run as Administrator.
In the DOS prompt window you will need to input specific information including the path and the file name. The following is a template for the command: regsvr32 "\FileName.dll"
It is important to note that path is the actually location or directory of where the file is located. Filename is obviously the name of the DLL file you will be registering. Below is a sample command: Regsvr32 "C:\Windows\System32\example.dll"
Once the command is input into the Run field correctly, press Enter.
Once the DLL has been registered, you should receive a confirmation in the form of a pop up box. This message will list your newly registered DLL file and confirm that is was successfully registered into the registry.
To unregister a file use: regsvr32 -u "\FileName.dll"
