While opening file upload dialogue from website, “Folder not accessible, Access denied” error message comes-Collection of common programming errors

I am trying to upload files to my website.

Every time when upload dialog opens, it tries to open a default path “C:\Windows\system32\config\systemprofile”.

This path is not accessible by every user on all the machines except Admin user.

I even tried to set this default path to “My Documents” but i am not able to get this path runtime.

Thanks in advance !
