We are using version 1.5.0.3. Yes, we are using the same version on both the network and the local machine.
I will have someone get that _metadata folder for me since it is an outstationed location.
Just to give a little more backgroup, we have done a few thousand of these archives from GroupWise throughout our organization. This is the first we have seen this problem. As I mentioned, the archive viewer will run from the network location logged on to another machine. It just will not run from this one particular machine whether I run from the network or copy it locally to the pc.
I will get the _metadata folder to you as soon as I can.
