HP Update installations failed

Hi,

I am using HP Update to download needed critical updates for my printer. But recently, my sys admin at work placed restricitions on how programmes can be run on our systems. I need to locate the actual exe file downloaded, right click on it and install it using a specific protocol - it won't work through the HP Update window.

How can I find the downloaded update files? If I can find them, I can then install them manually.

Thanks!
