This function works on Microsoft Office 32bit. But when transferring to 64bit, the error "Automation error %1 is not a valid Win32 application" occured.
Private Function CreateUsingManifest(nameOfClass As String) As Object
Dim actCtx As Object

Set actCtx = CreateObject("Microsoft.Windows.ActCtx")


On Error GoTo InvalidManifest
Set CreateUsingManifest = actCtx.CreateObject(nameOfClass) 'Error here

Set actCtx = Nothing
On Error GoTo 0
Exit Function

InvalidManifest:
Err.Raise "Automation error %1 is not a valid Win32 application."
End Function

seems like Microsoft.Windows.ActCtx is the problem here. Correct spelled?

There is a couple of things to be considered:

1- did you check for the library to be present?
2- did you try to import it into your project?
3- are your O.S and .NET framework installed in 64 bit version? cause they will not interact ( 32bits with 64 bits ) in runtime from .NET unless you do ... Assembly synchronization

I'm using a 64bit OS right now. I installed here first my 32bit MS Office and it was working fine. Then I uninstalled it and replaced it with a 64bit MS Office and this error "Automation error %1 is not a valid Win32 application." pops up.

Sounds like you have a 32bit application trying to interact/launch a 64bit application. That does NOT work well, as seen by your error message. I'm guessing you're compling your VB app as 32bit.
