Greetings from sunny Northern Ireland!
I downloaded this game today and installed it successfully (it passed the integrity check) but when I try and start it I get the following error:
Kingpin.exe has stopped working
A problem has caused the program to stop working.
Please close the program.

The first time I ran the game I got as far as the gold planet logo, and all subsequent attempts to run it never get beyond my screen changing its resolution.
I'm running Windows Vista Ultimate SP2 x64, fully updated. My graphics card drivers are the latest as of the date of this post [nVidia 8800GTX 768MB - driver version 195.62].
I've tried running the game in compatibility mode (XP SP2), as well as ticking some of the other compatibility options such as "Disable visual themes" and "Disable desktop composition", and I've tried running it normally and with "Run as administrator" to no avail. I've also tried disabling my anti-virus software which didn't help either.
Any ideas would be greatly appreciated! I'm itchin' to smite some punk-assed bitches with my trusty lead pipe.
Thank you kindly!

The link to the nHancer site leads nowhere, but a Google search turns up downloads for the program on multiple sites (both 64 and 32 bit versions).

Hi. I've got Microsoft Surface Pro 2 and I've played this game some time before on that tablet. But now Kingpin - and Quake 2 - crash on start. Any suggestions how to fix this issue?

Sadly something I cannot answer personally, as I am not running that version of Windows.

You can change the Extension Limit value using Nvidia Profile Inspector (latest build can be found here: https://ci.appveyor.com/project/Orbmu2k/nvidiaprofileinspector/build/artifacts ).

Checking the values set by default with driver 382.05, it has an Extension Limit of 1B58 for Kingpin.
