I have an application in which MS Project is launched. The application works fine for most of the system in my organization. But in some systems I get an exception when trying launching MS Project, and MS Project is not launched

The following piece of code is used to launch MS Project
Dim prjApp As MSProject.Application = New MSProject.Application

The exception I get in some systems is
System.Runtime.InteropServices.COMException (0x80010001): Creating an instance of the COM component with CLSID {36D27C48-A1E8-11D3-BA55-00C04F72F325} from the IClassFactory failed due to the following error: 80010001.

All systems have similar MS Project versions installed.
Even in those systems, I am able to open a project file on double clicking an mpp file. Can I know what is the reason for this issue.

Thanks in advance.
