Error loading type library

[napasa]

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)).

Can you let us know more about when and where you see this problem:

• Version of Office installed
• Version of Windows used
• Whether other file types (e.g. docx, xlsx) convert
• Whether you see this all the time or just sometimes
• Does this happen for a particular type of document (e.g. ppsx files, or large files)
• Are you running from the command line, or through a service
• Whether you've performed an online repair of your Office installation

Regards Vittal

If running an Office repair doesn't work, does the following thread help: https://social.technet.microsoft.com/wiki/contents/articles/18919.c-ppt-to-pdf-unable-to-cast-com-object-of-type-microsoft-office-interop-powerpoint-applicationclass-to-interface-type-microsoft-office-interop-powerpoint-application.aspx

Thanks your response. Wow! It works good when I run it on Power Shell. I run it on git-bash before. emmmm, maybe you can add more details to tell user to run it on Power Shell. Another question, do you consider to support PDF file to Office doc file? I know Word2013 could support it. Thanks vittal response

[napasa]
