SDK redistributable error

We have an application (.Net, vc9, 32bit) and we tried to test it on different machines. We installed the maching sdk reditributable and we tried to run the release version of it, but we always got an error "Required component is missing". We tried to run ViewVideo sample from SDK, but same result.
We realized, that if we install the SDK developement package, our application starts working, but only on 32bit OS, on 64bit OS we sill receive the error message.
Can you help me what could be the problem?
