Installing a processor with heatsink attached?

Okay, I'm in need of help...serious help. I was cleaning a friend's computer out and I somehow moved the cpu while cleaning it's fan. The processor is now out and I can't figure out how to get it back in.

The problem is that the heatsink is attached to the processor. I can't put the processor in because the heat sink pushes the zif bar down before it even reaches the processor. Like I said I'm in need of desperate help, this is not my computer and I need to get it fixed in next few hours. What should I do?

Any help would be great. Thanks in advance.

i bet the reason the heatsink is attached is because of the thermal cream that they have in between the processor, maybe use some rubbing alcohol to remove it?

How did you manage to move the CPU !?

Thanks guys.

I was really worried because I tried putting it in while the zif bar was down and I bent a bunch of pins. I put the pins back in place, and then used a hair dryer to loosen up the stuff and used a twisting motion to get it off. I tried pulling at first, but that didn't work. Anyways I got it all fixed in time and the computer works better than ever. It was overheating due to tons of dust.

Again thanks a million.
(and I have no idea how the cpu moved while I was cleaning it's fan, just happened no idea...)
