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

My guess is that Excel is installed in the systems that are not getting the error and it is not installed in the system that is getting the error.

I thought of that too and I contacted my client and he said that the Excel is installed. Then about an hour after I posted this question he called and said that his entire Office is behaving oddly whatever that means. So I instructed him to reinstall the Office and well see what happens. Thanks for your response
