You’ll most commonly need to use this method to register DLLs which came with third-party programs that are supposed to interface directly with system-level resources (e. g. , Command Prompt).

The “entry point” error isn’t so much a problem as it is a confirmation, as seeing this error means that your DLL doesn’t need to be registered.

If you installed a program for which you want to register a DLL, for example, you would go to the program’s installation folder (e. g. , “C:\Program Files[program name]”).

Since most DLLs have difficult-to-remember names, consider leaving up the Properties window when you’re done here; that way, you’ll be able to copy the name later.

For example, if your DLL file is in the “SysWOW64” folder that’s inside the stock “Windows” folder, your command would look like this: cd C:\Windows\SysWOW64

For example, if the DLL’s name is “usbperf. dll”, your command would look like this: regsvr32 usbperf. dll To copy the DLL’s name at this point, re-open the folder with the DLL in it (the Properties window should pop up), then highlight the name in the text box and press Ctrl+C. You can then paste the name into Command Prompt by pressing Ctrl+V. If the DLL is either already registered or unable to be registered, you’ll see the “entry point” error pop up instead of a confirmation message.

Type in regsvr32 /u name. dll and press ↵ Enter. Make sure to replace “name” with the DLL’s name. Type in regsvr32 name. dll and press ↵ Enter, again remembering to replace “name” with the DLL’s name.
