App-V 4.6 client has been tested extensively with pre-4.6 sequenced packages. If you’ve 4.5 RTM packages which use MSI for deployment, then they’ll have to be updated (4.5 CU1 and SP1 MSIs aren’t affected by this). There’re three ways to update 4.5 RTM packages:

  1. Use MSI transform that’s placed on Microsoft Download Center
  2. Use App-V 4.5 CU1/SP1 or App-V 4.6 Sequencer to open your package and generate new MSI
    • Open package in “Edit a Package” mode on 4.6 Sequencer
    • Select Deployment tab
    • Check “Generate Microsoft Windows Installer (MSI) Package” option
    • Save package
  3. Use App-V 4.6 Command-Line (CLI) Sequencer to overwrite your MSI with new one: SFTSequencer /Open:"package.sprj" /MSI. You can get more information about opening a package in CLI here. You could also write a batch script to convert multiple MSIs using option 1 and 3. You could get the Power Shell tool from here.
