Getting “Activex Component Cant Create Object”

Question

I am trying to call C# function from VB Script code, I am getting "Activex Component cant create object" error.

I have done the following.

1. Created class library with ProgID, and Comvisible True and strong named
2. Registered the dll using RegAsm.exe /codebase dllpath ( Dll registered successfully, I am able to see that in Registry)
3. Creating object using VB Script code and calling C# function as below.

Option Explicit
Dim testwfhandler
Set testwfhandler= CreateObject("CoreComponentWorkflow.WorkflowHandler")
If Not testwfhandler Is Nothing Then
    Call testwfhandler.test()
End If
Set testwfhandler= Nothing

Am executing this VB Script from third party application (Tridion workflow) installed in my server.

Don't know why am getting the above error,when i execute the same code from the server directly, it works fine.

test() this function will just create one log file and add some text inside that.

The answer is already provided through the comments but I figured it makes sense to suppy a real answer so that others can easily find it back.

Depending on how your VBScript is loaded/executed you should register your DLL using the 32-bit or 64-bit version of RegAsm.exe.

On a 64-bit OS, you should find the 32-bit version of regasm in, C:\\Windows\\Microsoft.NET\\Framework\\v4.0.30319\\RegAsm.exe

and 64-bit version of regasm should be in, C:\\Windows\\Microsoft.NET\\Framework64\\v4.0.30319\\RegAsm.exe

If you want to run the VBScript yourself in 32-bit mode on a 64-bit machine see How do I run a VBScript in 32-bit mode on a 64-bit machine?
