It’s therefore quite possible to publish those interface standards for other programs to use and, if so, then that DLL file can easily work with other programs. How dll competible for mor than one program at server sideĪ DLL file is simply a library collection of routines with defined entry points and parameters for the most part. In the rare instance that you need one and can’t find it on the Website of the program in question you might try… 🙂Īs mentioned above, all of the library files you need should have been provided by the programs that require them. I guess the bottom line recommendation from Computer Knowledge would be to avoid this process if at all possible.

It’s possible this procedure may fail in which case you may need information from the developer of the library. Once there, you will have to issue a command of the form…

In summary, if you choose to manually register a library file you will have to restart your computer in command prompt mode (called DOS mode in some cases). Indeed, it just might be easier to reinstall the application in question and let its installer take care of the registration process as part of the install. The process is non-trivial so you should study the referenced page quite closely if you are going to attempt to register a library file. You can find the full details about how to use the REGSVR32.EXE file at this Microsoft link… While this is rare, when this happens you may need to “register” the library file manually. And, if you just copy the DLL or OCX file back where it came from the system may not recognize it even if it’s in the proper place. When this is done the library’s registration with the system no longer applies. In this case, if you uninstall one of the programs its uninstall routine may delete the library in question not knowing that another program needs it. Sometimes, if multiple programs are using a DLL or OCX file the system does not know about all of them.

(Some DLL or OCX files are self-registering.) This process tells the system the libraries in the file are available for more than one program to use. When a program installs a library (DLL or OCX) file the program’s install routine will typically “register” the file with the system. Rarely, one needs to be re-registered with Windows. OCX and are distributed with programs that need them. These files typically have the extension. Most programs use some form of library files to hold common routines used by multiple parts of the program.
