So welcome to Informix first!
libbsapsm.dll is under %informixdir%\bin directory, not lib, on Windows - for a reason I'm not quite clear about right now.
The fact that you're hitting this problem trying archecker would implicate you already successfully created a backup - which also would have utilized this dll. Correct? And if so, did you use onbar or ontape?
So problem might be archecker.exe specifically looking for the lib at a place where it doesn't reside?
Maybe copying the lib to the lib directory would solve this?
Apart from all this: considered using Informix on Linux rather than Windows, or any particular reason it should be Windows?
HTH,
Andreas
