dll wont open

[adi_online]

Hi everyone,
I want to access a dll (librtlsdr.dll) using openlibrary. However when i try to it fails to give me a handle. I have tried accessing other dll's and they work fine. I thought it might be a corrupted file or wrong version. I have tried different rtl-sdr dll and i get the same error. Could someone explain what I am doing wrong here:

a simple one liner: libNo.i=OpenLibrary(#PB_Any,"d:\librtlsdr.dll")


Thanks

Where do I get this dll?
Have you counter checked if it's for the right architecture (x86 vs x64)?
Which PB version? Windows version?
