APP-V exclusion in registries

October 8th, 2012 No comments

Last week I was playing with application virtualization. I do have experiences with VMWare Thinapp applications. I already did couple of those virtualized applications. When I was forced to use App-V to create virtualized application I needed to make one application and I needed make this application to write registries into real registries and not to virtual ones. I thought it would be same as in VMWare Thinapp. That means I would expect to set some “isolation” mode on registry branch.

Problem is that you can define only two modes in App-V for registries:

  • Merge with Local Key – This will merge real registries with virtual ones. Change will be written into virtual registries.
  • Override Local Key – This will show only virtual registries to application and changes will be written into virtual registries.

In VMWare Thinapp there are isolation modes (for file system structures and also for registries) defined as following:

  • Full – Real are not shown. Any modification goes into virtual. New elements go into virtual.
  • Merged – Real are shown. Modification of virtual goes to virtual. Modification of real goes to real. New elements go to real.
  • WriteCopy – Real are shown. Modification of virtual goes to virtual. Modification of real goes to virtual. New elements go to virtual.
