jacob - Can't co-create object

Question

My environment is Java 7, on Windows 7 - 64 bit. So here's my requirement and procedures I followed

1. I wanted to execute a library called test.dll from Java
2. I first downloaded the latest version of jacob, and put them within a folder, which is included in the Windows environment variable PATH.
3. I registered the test.dll using regsvr32.exe under C:\Windows\SysWOW64 (it was successful!)
4. I am running jacob from a webapp, so I made sure that WEB-INF/lib has jacob.jar in it.
5. I also set a java System property - -Djava.library.path=c:/dev/jacob/jacob-1.17-x64.dll (This is where I have kept the jacob-1.17-x64.dll)

still I am facing

com.jacob.com.ComFailException: Can't co-create object
    at com.jacob.com.Dispatch.createInstanceNative(Native Method)
    at com.jacob.com.Dispatch.<init>(Dispatch.java:99)

I have gone through many of the SO posts but none of them have helped me so far

can anyone please guide me to the solution?

A similar problem for me was solved by changing the jdk from a 64-bit to 32-bit.
