Hi catflap001 ... this is a valid file.
The gdiplus.dll file is a component of the Microsoft Graphics Device Interface Library that handles graphics components for image handling, anti-aliasing, filling gradients, etc.
Not sure why it is on the D drive though.
Try this first
This maybe an issue with a system file being corrupt.
You can try a couple things.
Right click your start button and select Command prompt (Admin) to bring up elevated Command prompt.
In Command prompt type sfc /scannow and press enter.
Restart the computer.
If that doesn't work then try this,
Right click your start button and select Command prompt (Admin) to bring up elevated Command prompt.
In the Administrator: Command Prompt window, type the following commands.
Press Enter key after each command:
DISM.exe /Online /Cleanup-image /Scanhealth
DISM.exe /Online /Cleanup-image /Restorehealth
Important: When you run this command, DISM uses Windows Update to provide the files that are required to fix corruptions.
To close the Administrator: Command prompt window, type Exit, and then press Enter.
Restart your computer.
