The finished compiled file is in the attachment.
If you run 'CurrentDirectory.exe' by double-clicking the mouse, the correct path of 'CurrentDirectory.exe' file location will be displayed.
But if you open this file through the x64 context menu, the path will be 'C:\Program Files (x86)\XYplorer', which should not be the case.
Opening a file via 64-bit context menu:

If the file is launched by double-clicking or via the 32-bit context menu, the GetCurrentDirectory function returns the correct value:
