My team have been struggling with COM Component issue
for about one week, it almost frustrated the developer, me and project manager.
Uff.. after intense amount of googling and trial method, several time repair
and installation of office, the problem was still bugging all the team members.
Finally the issue was resolved with couple of settings in Registry. The real
cause of the issue was a mystery. Finally we succeeded to identify the reason
for the issue and then killed the exception.
Exception
thrown by the system:-
Below is the most boring exception frustrated me every
time when I debug the code
System.InvalidCastException was unhandled
Message=Unable to cast COM object
of type 'Microsoft.Office.Interop.PowerPoint.ApplicationClass' to interface
type 'Microsoft.Office.Interop.PowerPoint._Application'. This operation failed
because the QueryInterface call on the COM component for the interface with IID
'{91493442-5A91-11CF-8700-00AA0060263B}' failed due to the following error:
Error loading type library/DLL. (Exception from HRESULT: 0x80029C4A
(TYPE_E_CANTLOADLIBRARY)).
Source=Microsoft.Office.Interop.PowerPoint
