COMException error, class not registered

Expand Post »
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.

Re: COMException error, class not registered

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.
