activex component can't create object on a small exe coded on vb dot net

[C# Programming]

Hello,

our coder created an application on vb dot net that opens another exe file with process process.start command, the small exe he coded only checks for credentials and asks you to select the branch you belong to from a list of branches.
the program always showing Activex component can't create object, and all the articles on inet did not help so far, any one got any idea, i could post the code but it's long for a forum

Thanks
