Whenever I try to install a Windows component (ex. an IIS Module) in the control panel, it runs for a bit and returns:

An error has occurred. Not all the features were successfully changed.

The event viewer gives a clue:

Ran out of time while expanding file specification \?\GLOBALROOT\Device\HarddiskVolumeShadowCopy24\Windows\softwaredistribution*.*. This was being done for the WUA subscriber.

Operation: OnPostSnapshot event PostSnapshot Event

Context: Execution Context: Shadow Copy Optimization Writer Execution Context: Writer Writer Class Id: {4dc3bdd4-ab48-4d07-adb0-3bee2926fd7f} Writer Name: Shadow Copy Optimization Writer Writer Instance ID: {8148cbcf-fe05-4607-821f-ec024a4fad7f}

Googling this turns up very little of substance. This is a Vista machine which was recently upgraded from XP.

Any ideas?

Thanks, Tom

You could try to temporarily disable the Volume Shadow Copy service (Windows Services) and install the IIS module. Before you do that, create a system restore point. You'll never know.

Thanks! That worked. Well, more precisely, I had to disable it, install some things, re-enable it to install others, and after some trial and error it all got installed. Very painful. Thanks for the tip. –  Tom Lianza Jul 31 '09 at 2:21
