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

Thanks, that did the trick. It was working a couple of days ago and since then there’s been a Windows update (AFAICR) and I also went part way through installing RAD Studio 2007 which installed the .net SDK v2…
