It's quite simple, you can boot your Windows computer into Safe Mode with Command Prompt, then download the .dll file online and replace the old .dll file located in C:\Windows\System 32\.

However, if you can't access your computer even in Safe Mode, you'll need to download the .dll file from another computer and copy it to a USB drive. Then, you can apply various methods to replace the .dll file.

To accomplish this, you'll need a USB Boot drive or a DVD. You can refer to Mytour's guide on creating a bootable USB with Rufus. Let's assume the file is gdiplus.dll .

The first step is to copy the gdiplus.dll file to the Bootable USB drive, then follow these instructions:

- Insert the Bootable USB drive into your computer.

- When the Windows Setup window appears on the screen, press the Shift + F10 keys to open Command Prompt.

- Type regedit into the Command Prompt window and press Enter.

- In the Registry Editor window, select HKEY_LOCAL_MACHINE, then click File =>Load hive .

- Now, a new window similar to File Explorer will appear on the screen. Here, you can find drives and everything else just like in File Explorer.

- Copy the gdiplus.dll file and paste it into C:\windows\System32\ .

If your Windows installation drive is not C:\ on your computer, simply replace C:\ with the name of your Windows installation drive.

- If you encounter a message stating that there is not enough memory, you can perform this task in Command Prompt.

- In the Command Prompt window, enter the following command:

copy D:\gdiplus.dll E:\windows\system32\gdiplus.dll

- In the command above, D is the USB drive name and E is the Windows installation drive name. If your USB drive and Windows installation drive are different, you can replace D and E with different characters.

- After completing the task, restart your computer and try logging in to see if the logonui.exe error persists.
