Error accessing COM components

by

Problem solved!

I have previously installed Office 2010, so there are some inconsistences in Windows Registry.
To fix them, open the regedit and find for the CLSID from the error.

You will find something like that for the second error:

HKEY_CLASSES_ROOT\Interface\{00020970-0000-0000-C000-000000000046}

With the subkeys:

  • ProxyStubClsid
  • ProxyStubClsid32
  • TypeLib

Take a look at the (Default) and Version values inside of TypeLib.

Now find the node below, using the (Default) value as <TypeLib ID>.

HKEY_CLASSES_ROOT\TypeLib\<TypeLib ID>\<version>

As child of this elements you will find more than one element, one of then is the Version of the first registry. If you inspect the others elements, you will find that they point to nothing. Remove the others!!! It’s solved!
