Failed due to the following error: 80040154

(VB.NET) I've been searching for 3 days trying to figure out why this is happening, but I'm out of luck and out of my mind! Anyone have any idea why this is happening? I get this error as soon as I open the application. It works fine on my machine, but when we installed it on a test machine, we get this error.

3:46 PM -- An error occurred creating the form. See Exception.InnerException for details.  The error is: Retrieving the COM class factory for component with CLSID {857C49E7-ADC6-11D1-98C1-0060948CAA0A} failed due to the following error: 80040154.

And the line 35 is this:

        <Global.System.Diagnostics.DebuggerStepThroughAttribute()>  _
        Protected Overrides Sub OnCreateMainForm()
            Me.MainForm = Global.SLSClaimantWorkbook.SLSClaimantWorkbook ' line 35
        End Sub
