Grimrock

Okay so installed the game after i downloaded it off gog.com and it works on my work computer. but when i took it home to install it, this window popped up:

E:\Legend of Grimrock\Legend of Grimrock\d3dx9_43.dII is either not designed to run on Windows or it contains an error. Try installing the program again using the original installation media or contact your system administrator or the software vendor for support.

and i did try reinstalling it. I have windows 7, 32bit, and i have played games like skyrim and protal 2 on my computer no problem so i seriously doubt its the system requirements.
and if someone could help, im not very sure of some computer terms, generally i just install a game and play it, i have never had to mess around with files and stuff.
thank you!!!

+ 10 points of awesomeness if anyone answers me

also just to add, i know this problem has come up before, but i didnt understand ANY of the ways to fix it. just some simple instructions would be awesome, im itching to play it

There is a bug in the GOG installer. Just remove the d3dx9_43.dll from grimrock folder and it should work. If it still doesn't run make sure that you have the latest DirectX end user runtime from Microsoft installed.

Thank you so much! I got to play like 2 seconds of it at work (when i shouldn't have been xD ) , and i was so keen to play it for real. and i told 4 people about it, all of which have gotten to play it haha. im very keen ^.^ again thank you

Removing the .dll fixed the problem for me. Been playing for 120 mins with no problem except some slight lag in places. Killer game btw!
