Windows 7: Message: Cannot find the file specified Appdata

I was trying to download a driver for my printer from the HP website and the following message came up:

Cannot find the file specified
and above it was:
c:\users\<myusername>\appdata\local\temp\7zs4df5\setup\,,\setup\hpzprl40.exe

I've had a look and the appdata folder is there under my username
I have had a lot of problems lately with saving files etc and a message about Appdata. I am desperate to use my printer and need to download the driver if someone could take me through step by step what to do that would be great.

First of all, that is a temp folder which gets cleaned out on occasion. Download the driver to a folder HPDrivers under Documents. Then update the driver from the device manager and browse to the new driver location...

I tried saving it to my documents instead of running it and it still wouldnt do it. i don't know alot about computers so if you could dumb it down a bit that would be great thankyou

What printer are you trying to download the software for? I'll go to the HP site and see how you would need to do it. And what browser are you using? Internet Explorer?

My printer is a HPf450 and im using internet explorer. I would really appreciate any help!

This is the link i am using to download the driver.

I have had a few error messages about app data when i have been opening microsoft office word also. Don't know if this has anything to do with it?
