i downloaded both KB AP and Legends (gold edition) through steam. Is there a way i could try to manually patch even though it's a steam install? steam automatically updates the game but.

Well 8600M is sucky card, but he has second 9500gt on desktop which can run KB perfectly. Its pretty much possible that OS is the cause.
] Anyone playing this game on XP 64 bit??
in my country there is no even such version ,its pretty uncommon and there is no guarantee that 32-bit game wil work on 64 bit. This game had problems with 64 bit from start, on windows vista 7 there was done a lot to make most programs run on 64 bit but on XP i doubt in it. Compatibilty was always main disadvantage of 64 bit system.

To the OP,

Your hardware (both desktop and laptop) should be able to play the game just fine, so the only thing that is common in both that may be causing the problem is your Win XP 64-bit OS.

If it is any help, you did mention that you plan on trying out Windows 7. I have Windows 7 Home Premium 64-bit as my OS on my laptop and it runs KBAP just fine.

try that
some people had troubles with patch 1.7

try 1.6
or lower
maybe that would help
just a suggestion

Well, I finally fixed the problem! Well, sorta.
I just updated my computers to windows 7 ultimate x64. My macbook pro uses the 197.16 drivers and everything works fine. It hasn't crashed on my desktop either (also running windows 7 ultimate x64 now). I've played it for about 2 hours so far straight with no crashes! :grin:

It has been a frustrating week, but I can now finally enjoy this game. It's pretty awesome!

Thanks to everyone who helped!!!

So we can say confirm that this game won't run on XP x64 ^^

And we can confirm that the game is not broken ^^ is the windows xp 64 the broken one!!

I'm not sure what exactly might have been the cause of your issue, however, I can say for sure that King's Bounty: The Legend will run on WinXP 64 without issue. I've played almost the entire game so far.

However, I'm not sure if this is normal, but while playing KBTL both CPU cores are at 100% consistently while the game is running. I've got an AMD Desktop which I built myself bout 2.5 years ago. Has an Athlon x2 5600+, often OC'd to 6200 speeds. Videocard is Nvidia 8800GT using latest official drivers. 2GB Ram.

Whenever I get a chance to purchase and play Armored Princess I'll make sure to confirm that its working for me, if in fact it does.

I've been able to play everygame I've tried on XP-64. However, there is the occasional odd XP64 only issue. Such as with the Dirt 2 racing game. New versions of Games for Windows live cause a problem where the game is unable to create save game data at all. Giving a 'data is corrupted' error each time, even when attempting to start a new profile! Using older GFWL version fixes it, but, then you can't play on-line. Been 6 months, but, despite acknowledging the issue it still has not been fixed.

Similar problem with Guitar Hero aerosmith where you can't play the game starting from the beginning. However, if you use a save game that is a cpl lvls in the whole game plays fine without any other issues.

These are the kinds of problems you tend to run into with XP64, lol. Well, at least the kind I run into!

Is known that Windows xp 64bits cause problems on some games, but not always. That Armored Princess crashing issue must be a random one.
