I am trying to implement AppV on my SCCM 2007 R2 environment but I am not familiar with packaging applications with AppV aka SoftGrid. I have everything setup the SCCM 2007 side and need to build the virtual package to upload to SCCM. Can someone explain to me which software I need to download in order to build this AppV? Can someone point me to an online resources that steps me through this process?
