0x80040154 class not registered and that is all we can get out of our Insert

My current code ran in VS2003 on a XPpro machine. I transferred it to a Vista 
machine and had to purchase VS2005 . I made the changes and the code ran. I 
made additions over several weks and the code still ran . I did not run the 
code a gain for about a month and then the code would not run on the Vista 
machine so I installed VS2005 on an XPpro PC and the same then code compiiles 
and runs fine. 
 

Both PCs have Ofiice 2003 Pro on them and no other versions of Excel or 
office.

 

It as if one of  the MS regular Vista updates made a change causing the code 
not to compile.

 

My code is in Visaul Basic

 

These are the first lines of the code

This is the error message:

Error occurs at the line :

Does any one have any ideas how to fix this problem?

Hi everybody,

An OWC Spreadsheet is placed on a windows form in my C# project. This
application was written on a XP 32bit machine and is working smoothly
meanwhile. Thanks to a great support in this board!

Now I had the chance to install XP 64 on one of my machines and was
curious whether my app would work on that as well. After installing
the OWC from the MS Homepage, the build of the application went fine.
When I started it in the IDE it highlighted the line:

((System.ComponentModel.ISupportInitialize)
(this.axSpreadsheet1)).EndInit();

the message is.

  Message="Class not registered (Exception from HRESULT: 0x80040154
(REGDB_E_CLASSNOTREG))"
  Source="System.Windows.Forms"
  ErrorCode=-2147221164
  StackTrace:

System.Windows.Forms.UnsafeNativeMethods.CoCreateInstance(Guid& clsid,
Object punkOuter, Int32 context, Guid& iid)
       at System.Windows.Forms.AxHost.CreateWithoutLicense(Guid clsid)

I browsed the internet without any luck. There was a little bit about
SQL Server, but that was about it. If you have any idea it would be
great if you can share it with me.

I am working in MS Office Accounting Express 2007 and MS Office Word 2003 and 
trying to either send a quote as an email or save as a Word document. This is 
when I am getting this error.

Is there a compatability issue with the Accounting software and this version 
of Word?

How can I get this fixed?
