HP PhotoSmart Essential.msi Missing Error

Hi,
I am a HP Photosmart C4280 user in windows7. I was using it for past two months, but now I’m having this problem.
HPPhotosmartEssential
An installation package for the product HPPhotosmartEssential cannot be found. Try the installation again using a valid copy of the installation package "HPPhotosmartEssential.msi".
When I tried to print a file, the error message comes up telling that the file “HP Photosmart Essential.msi” is missing. I didn’t receive any help from HP service Centre either.
Please help me.
Thank you
