So I heard a lot of people with graphical issues, but they all seem to talk about getting a black screen with nothing loading or effects in game going crazy. My issue is slightly different. When I try to load either version of the game, demo or full, I get:

"Unable to execute file:
C:\Program Files (x86)\Nifflas\Knytt Underground\Knytt Underground.exe

CreateProcess failed; code 14001.
The application has failed to start because its side-by-side configuration is incorrect. Please see the event log for more detail."

I do not believe there is any way I can see the event log so more details are hard to get. I'm running 64 bit windows with an Nvidia Geforce GTS 450.

Any assistance or details on the issue are greatly appreciated. I will continue looking into stuff about graphics cards, but I don't see similar reports around here so I suspect that isn't the issue. All 4 of the graphic drivers I need are supported, my stuff up to date, and card pretty far from out of date.

A small update on this issue. My laptop is giving me the exact same error. This is really upsetting because my laptop is in almost every way different from my desktop. The only similarity that comes to mind is windows vista, but even then it's 32 bit vs 64 bit. Given I can find no one else with this error, it seems really odd I would get it twice in a row.
