Yes, you have a 64-bit processor. You can install a 64-bit version of Windows.

Just for future reference the manufacturers website is usually your best bet to check feature compatibility.

Look for 'Instruction Set' to find out whether the hardware supports a 64-bit operating system version.

I want to install atrial version of Adobe After Effects, but Adobe After Effects only runs on 64-bit Windows. Can I install Windows 64-bit on this computer?

There are definitely 64-bit drivers for that computer. It's not old enough to not have them. HP was writing 64-bit drivers for old models when Vista was still in beta.

If you have a choice, always choose Windows 7.

Windows 7 x64 should work fine for you. Also, windows license keys work for either the 32-bit or 64-bit version, so if you can find a 64-bit installation disk, you don't even need to buy a new license. You can't do an in-place upgrade though.
