Just thought I'd add that I have the same issue. 64-bit version on the download page on windows 7. A quick google search seems to maybe indicate that having Visual Studio installed is the problem, but I have no time to look into it now. 32-bit version poses no problems. edit: Actually, I figured it ...

Hmm. This is true; I had forgotten about this feature. It won't have the same neatness of the layout as numpad, but it might do the trick. If it worked for you, it should work for me, I guess. Thank you for you help.

I've been wanting to give the two Indiana Jones games a try, but upon reading further about them today, I noticed they have a fighting element to them using the numpad. Now, I use a laptop, and naturally don't have said numpad. Is it feasable to play without one?
