How to Install .DLL Files

Installing .dll files is a simple process that can be done in a few minutes. You can install .dll files directly to Windows, or to the software installation folder where the application .exe is located.

On a 64-bit Windows system you can install 32-bit and 64-bit .dll files. Check compatibility.

System Installation

Installing .dll files to the Windows system folder is the most common method. Simply place the .dll file in the appropriate Windows system directory. If the .dll file already exists, make a backup before installing.

If you installed 32-bit software, 32-bit .dll files may be required.
  1. Place 64-bit DLLs in the '/Windows/System32' directory.
  2. Place 32-bit DLLs in the '/Windows/SysWOW64' directory.

Software Installation

Installing .dll files where the software's .exe file is located offers several advantages. Using this method, the .dll file is isolated to the software, rather than a shared resource in the Windows System.

In some cases, there may be a /plugins or /dlls folder in the software directory for installing .dll files.
  1. To locate the .exe file, right click the application shortcut.
  2. Right click and select properties.
  3. Copy the target location. (without .exe)
  4. Navigate to the target location you copied and place the .dll files into this folder.

Redistributables

Redistributables are official packages that include necessary .dll files required for running applications. Using DLLme, you can lookup a .dll file and see if there are any suggested redistributables or software packages that contain the .dll file.

  1. Search for the .dll file at DLLme.com.
  2. If a redistributable or software package is mentioned, download and install the package.
  3. Click here to view a list of redistributables.
Did you know...

Not all DLLs need to be loaded when an application starts. Developers can use "delayed loading" to load a DLL only when a specific function is called, improving initial startup time.
