Doesn't seem to work with the retail version of the game.. Crashes a few seconds after the DOS box comes up.

[uncajesse]

If you have Vista, you have to run it as administrator (and no, being logged in as administrator is NOT how you do that). Google for: UAC. I'm not saying that's the problem, but for people with Vista (i'm not saying you have vista) that's usually the problem.

[Shadow-Link]

I've got vista and it didn't work for me. I've turned off UAC and right clicked on the exe and selected 'Run as admin'. It still crashes at the same place.

It could be the DVD version differs from the steam version, i wouldn't know.

some one could PM me with info on the DVD version and i might be able to help.

[Vecis]

Great, i guess this will help a lot of people.
Weird about Steam version, but well, couldn't that be steam.exe which is stopping GTA from launching? Just a guess.

[opium_addict]

No, the only issue i see is that the GTA exe for DVDs is different from the steam version, which is possible and understandable.

Hello Mr opium_addict.

Nice work

Hum i searshed a bit too and humm.

Maybe we could juts patch the "jz" (Jump if Zero) @0x403494 with 0x90 (On 2 BYTE) or change it to a "jnz" no ?

CODE

.text:0040348D                 call    sub_402CD0 .text:00403492                 test    al, al .text:00403494                 jz      short loc_40344D

[opium_addict]

You can do what you wish

edit: disregard my previous statement

I'm working with a DVD version.

And there is something I can't understand. Your Injector and my old one can't find the process. Endless loop on the SnapShot stuff. That's strange

[opium_addict]

Well i don't know why you are having problems, but yes i figured out the gta DVD and steam exe seem to be identical.

If there is errors its probably something on your side (Vista UAC or anti-spyware etc)

both have MD5 hash:

CODE

Input MD5   : 9FA1C2A3F2932D46538BC14E715CFCCC

they are identical.

[Shadow-Link]

is it possible that it's not working because I am running vista 64 bit?

[opium_addict]

It could be, try running GTA4 and my program in 32bit compatibility.

although it is true you may be able to compile my program (with tweaks?) to run under x64 arch i am not sure as ive never worked with x64 before,
nor am i familiar with it in any way.

32bit compatibility should work fine however.

[Shadow-Link]

Tried it on vista 32 bit (laptop) and got the same error.. May I ask you what O/S you use?

Edit: Compiled it on my own system using vs2008. Still doesn't work..

Think I'll need to create a XP partition then...
