ctl3d32.dll problem in Windows 7

Hello there!

I just experienced some strange problem. Some normal custom controls distributed with my application don't work in Windows 7, however in Windows XP they are fine. I found out that controls and some dlls could not be registered because ctl3d32.dll is missing. That's not true, because I checked and I found it on two places (System32 and SysWOW64). So ctl3d32.dll is missing but it is here (!!??) and I cannot register some ocx and dlls. Have somebody experience about this problem? What's going on?
Thank you in advance!

try setting you app's target cpu to x86

Project-->Properties-->Compile-->Advanced Compile Options-->Target CPU

Some dlls are from 3rd party developer and all my components are written for x86. Is there any workaround? Is this ctl3d32.dll really so important or can I bypass somehow?
