I have published HP driver updates using a cert from my PKI..

I have added the cert to group policy and deployed it to all systems trusted publisher..

I have downloaded the updates created a deployment and now receive the following error in the updatehander.log

There are problems with HP catalog en applicability rules.. sometimes they look for existance of a dll and this is not always right..

Using HP catalog with WSUS works only when you pupblish manual items to wsus and expire old ones manually..

It can still save you a lot of work creating packages for laptops for instance quick launch buttons but you cannot rely on detection mechanism..

Would be nicer to use detection, reporting and the HP cert but this is all not in the package..

What I wanted to do is use these updates in OSD task sequence building machines always with latest drivers...

Maybe somebody got this working but it looks like a bridge to far at this moment..
