What are ISSetup.dll Error Messages?


Dynamic Link Library ISSetup.dll Errors

ISSetup.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like ISSetup.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like Setup.exe - to follow. These files were created so that multiple programs (eg. Realtek High Definition Audio Codec (Windows 7 / 8/ 8.1/ 10 64-bit)) could share the same ISSetup.dll file, saving valuable memory allocation, therefore making your computer run more efficiently.

Unfortunately, what makes DLL files so convenient and efficient, also makes them extremely vulnerable to problems. If something happens to a shared DLL file, either it goes missing or gets corrupted in some way, it can generate a "runtime" error message. Runtime is pretty self-explanatory; it means that these errors are triggered when ISSetup.dll is attempted to be loaded either when Realtek High Definition Audio Codec (Windows 7 / 8/ 8.1/ 10 64-bit) is starting up, or in some cases already running. Some of the most common ISSetup.dll errors include:

Your ISSetup.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Realtek High Definition Audio Codec (Windows 7 / 8/ 8.1/ 10 64-bit)), or deleted by a malware infection. Furthermore, ISSetup.dll file corruption could be caused from a power outage when loading Realtek High Definition Audio Codec (Windows 7 / 8/ 8.1/ 10 64-bit), system crash while loading ISSetup.dll, bad sectors on your storage media (usually your primary hard drive), or quite commonly, a malware infection. Thus, it's critical to make sure your anti-virus is kept up-to-date and scanning regularly.

Step 3: Perform a Windows Update.

  2. In the search box, type "Update" and press "ENTER".
  3. In the Windows Update dialog box, click "Check for Updates" (or similar button depending on your Windows version)
  4. If updates are available for download, click "Install Updates".
