COMException error, class not registered

Question

This is the error I get:

An unhandled exception of type 'System.Runtime.InteropServices.COMException' occurred in system.windows.forms.dll
Additional information: Class not registered

And this is the line it points me to:

CType(Me.Comm1, System.ComponentModel.ISupportInitialize).EndInit()

Does anyone know why I would all of a sudden start getting this error?
Does anyone know how to fix this?
I was adding/removing some .dll files from the project in order to find out why another issue wasn't working and I am thinking that could be the issue.

I will continue looking at the .dll files to see if that is the issue.

Please let me know what you think, Thanks.

If you were removing dll's then you removed the (Com1.dll ?) and it was needed by the program. Whatever, then you will have to re-reference it.
