Android Question

as ive read the other related problems posted here on this page, its slightly different from mine. everytime i tried to install camera 360 on my phone, after downloading it says that 'insufficient storage available'. i deleted the not so used application i downloaded, but still, same result. i erase the files on my sd card but still, it always come up with the same result. INSUFFICIENT STORAGE AVAILABLE. the first day i bought this phone, i immediately downloaded camera 360 but for some reason, i deleted it. then what i tried it again, there it started saying insufficient storage available. and i really do wonder it only appears everytime i downloaded it unlike on the other apps ive tried. please please do help me. thank you
