Yeah, I re-installed the game twice with the error returning each time so that isnt really a fix for it either. There has to be something causing it to occur. So far I havent seen any common denominator that could be blamed for it. It is happening on a wide array of hardware setups and software configurations. Maybe the discs dont read well on some DVD drives? What kind of DVD drives do you guys have?

It HAS to be file corruption, because ppl have reported that installing the game from another source has helped. I had the same problem but I downloaded the game and now ive played it 8 hours and no crashes so far.

My friend just wasted 2000e for new pc, i will visit him today and install the game from my original discs and see if he gets the same error after playing a while.

1st: I own a legal copy of the game which I bought about a year ago

2nd: sorry for my english

3rd: I think I have a solution for the ZLIB20 Fatal Error (I'm still testing it and no crashing for now)

after months of reinstalling and everytime combining it with diferent patches and with different addon programs (like asi loader, SNTrainer and etc, because I love the custom addon features) I found after attending a mission that the game crashes in 100% of the time when you are at the airport with the ZLIB20 fata error. so I realized that every time i reinstalled the game 1st i changed the orig vehicles.ide,handling.dat,carcolor.dat and the vehicles.img with mine fully customized from the different sites files, so I reinstalled the game (again) loaded it with the custom programs and trainers, upgated it with the 1.0.4.0 patch and started it with the original vehicles, thye I went straight to the airport and the game doesn't crashed for a second, then I spent few days that way without any problem
After that I wanted to find why the game gets the ZLIB20 fatal error with the custom cars, because I hated the original ones, they are dull, simple and ugly and I love my downloaded custom ones !
so I started removing them one by one to find the one that causes the error (it happened to me before with different error, so I thought that is the problem) and with every car i started the game and spawned them with the trainer and one time by accident I loaded the "airtug" and the game crashed immediately!
It was still the orig one, so I found on the net custom made one http://www.gtagaming.com/downloads/gta-iv/vehicle-mods/3192 and changed it!
then i started the game and straight to the airport, no crashes, custom cars, custom features and I love it! Now I play it with a big smile on my face

Hope I've been helpful

Holy thread resurrection batman!

I'm glad you have got the game to run without the ZLIB20 error and your solution may work for some people.

This does not particularly help the people that never used mods and were running everything stock standard. I received this error without any modifications at all.

My ZLIB20 errors seemed to disappear after the second patch or so.

crack does not help, and I've also reinstalled the game 3 times now. how are some people never getting this error and others get it all the time.

Yea? Why? How? How it is possible?? I get that error in... 51 Seconds, lol. Anyways any GOOD way to fix it?

Guys I had the same error ZLIB20 and I also fixed it but I don't know if it will work for all of you. Some car mods can also be the cause for this error and that's was my problem so you're gonna have to check which one causes the error. Hope this one helped.
