Causes And Solutions To DLL Errors — 3 Comments

  1. Sometimes DLL errors are the fault of the developer. This can happen when they statically link to functions in a system DLL that do not exist in all versions of Windows. Even if they detect the Windows version and never actually call the function, Windows tries to preload it into memory in case the application will. When the function can’t be found, the application crashes. (usually when you first try to run it)

    This happens most frequently when the developer isn’t very experienced and only writes his software for whatever version of Windows he is using, tries to do some “fancy tricks”, doesn’t test it on anything else, and someone with an older version of Windows tries to run the application.

    There isn’t anything you can do to fix this type of DLL error, as a user. This is something that should be reported to the developer as a software bug.

    Another type of DLL error is when the particular DLL needs to be registered with the operating system in order to work. The file isn’t missing, it is right where it belongs, the correct version and everything, but it still just won’t work. This is something best fixed by someone with some experience with these things, as incorrect usage of regsvr32.exe can have some negative effects on your system.

  2. Really good article and comment. Personally I don’t encounter DLL errors often and neither do any of my customers. If I do encounter one, I find that the easiest solution is to reinstall the application or the visual basic/c runtime/environment library.
