SSAS: Class not registered (Exception from HRESULT: 0×80040154 (REGDB_E_CLASSNOTREG))

Today I got this error while trying to browse a cube from the Business Intelligence Development Studio:

The detailed error information told me that the connection failed, because the server actively refused it. Connecting from another pc worked perfectly, so it had to be a problem with my computer.

To solve this problem I needed to reinstall the OWC Component (Microsoft Office 2003 Web Components)
