Authenticode: error loading type library/DLL

I've just started having having this problem today.  What could cause this, a windows update?    Which dll is it trying to load?

Hi David

The authenticode action uses capicom.dll, which should be in your system32 folder. If it is there, try running regsvr32 on it.
