How to fix errors generated by wimgapi.dll

The wimgapi.dll file errors occur primarily while generating a boot image. It is also used to install Windows on new hardware with ease, as well as for updating existing installations. The OS is installed using the Windows Vista media disk, and WAIK loads first to create an environment for the OS to load as per the desired settings.

It helps in customizing the installation options and settings of the user without responding to any prompts. One of the core image files of WAIK is wimpapi.dll, which helps in creating advanced imaging tools. A majority of the third party tools include these files in their software. The problem occurs when the file is not packed in the software or when there is a file version mismatch.

To fix errors with wimgapi.dll, follow these steps:

  1. Download WAIK from the Microsoft website
  2. You have to burn the image onto a CD or DVD as it is distributed as an image file
  3. After burning the image to a disk, insert it in the DVD drive
  4. It will automatically read from the disk and recognize the version of the installed OS
  5. It will look for the WAIK folder and place wimgapi.dll in it; if the file is already present, it will overwrite it

Now try to create the image file, and if it still gives you the error, then you can manually replace the wimgapi.dll file. To achieve this, follow these steps:

  1. Click on Start, and then in the Run dialog box, type the path below:
    C:\Program Files\Windows AIK\Tools\x86
  2. Now copy and paste the wimgapi.dll file to the folders listed below:
    C:\Program Files\Windows Imaging

You can overwrite the file if it already exists and then restart the system. It is very important to restart the system as the imaging files are applied to the environment settings.

Depending on the version of Windows you have, you can download and install the version of WAIK and solve all the errors related to wimgapi.dll.
