How big is the MSI package itself? If the package is small enough could you attach the MSI package and send it to us. WE will verify why you are getting this error.
If this is not possible, is an eval version of this package available? If so, could you please send us the link?
By looking at the file extension I doubt its a COM Dll AppServices.dmc. It should 'nt try to register if its not. If its not then you may want to get rid of the entry corresponding to AppServices.dmc in the MSI TypeLib table. The error should go away.
What I meant was an entry corresponding to the component for AppServices.dmc. Again if its not really a typelib then you should'nt populate it since it fail to register. All COM servers need to have right entries in Class table. And if the setup also distrbutes typlib for that COM server then Typelib table needs to have entries too. Look in MSI help for details
