You are trying to use a COM control that is not registered.

From the error, it looks like your application is using some sort of COM object that is not installed /registered on the machine on which you are getting error.

For troubleshooting you can look into source code of form, try to find out what COM object its trying to create, which is causing issue. Then install required COM object on machine .

Use following links fro reference
Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG))[^]
I'm getting this error when I'm using COM reference in winform[^]

thank you so much for your valuable help...its getting me idea of my problem solution..i m trying to understand and registered COM com object on my machine.....
Please set the project platform target to x86. Since most of the COM you may be using in your project was built on x86. Project Properties-->Build-->Target Platform-->x86
