Excel Interop error

Question

Hey
I'm having a problem with running an application I made on another computer. This is the error message I'm getting:

System.Runtime.InteropServices.COMException (0x80040154): Retrieving the COM class factory for component with CLSID {00024500-0000-0000-C000-000000000046} failed due to the following error: 80040154

I searched it on Google, and found out that it means that I need to register that specific component in regedit, but I don't know how to do it, or where to find the component I need to register, so please help me.

I used C# in VS 2010 to make my application. One more thing, I don't know if it matters - I installed this application on 3 different computers, and this is the only one that gives me that error - it is a HP all-in-One computer.

Thanks
