MLApp Class not registered error

22 views (last 30 days)
Hi All,
I am writing a program and calling MATLAB from C#.
The had worked well until yesterday.
Since yesterday I get following error(unhandled exception during runtime)
at the line MLAppMLApp.MLApp matlab = new MLApp.MLApp();
the error is :
System.Runtime.InteropServices.COMException: 'Retrieving the COM class factory for component with CLSID {0C4A9B69-D348-4167-8456-C60532821B6E} failed due to the following error: 80040154 Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG)).'
Anyone knows how to solve this problem?

Hi Again,
I could solve my problem by using same malab release on the VS application.
The problem was that the COM was registered but the release was different from the
COm that my program in the was using.
Thanks Matlab support :)
