If the folder html is your website folder, the moodledata folder should not be where it is. It should be at D:\hosting\10150264\moodledata.
I can't say that I am an expert in this sort of thing, but you might give it a try. I think this mistake is made often enough, and it's really a big mistake, so the coders of Moodle created a check and an error message.
Do you know if your shared hosting account had the correct versions of php, and mySQL? I think Moodle 2.4's requirements are the same as 2.3.3+, but you should check. Do you know how to create an info.php file?
I assume that you might know how to answer these questions and do what I suggest, but let me know if you don't and need some guidance.
