At Microsoft we are continually receiving feedback from customers and improving our products, and as part of this process we review open issues and supply hotfixes as appropriate. In line with this approach, we just published a new Microsoft Application Virtualization KB article which addresses the following issue:
When you run the German version of Microsoft Application Virtualization 4.5, you cannot add or change attributes in the Open Software Descriptor (OSD) tab.
For more information and to download the hotfix see the link below:
