The preview of the MSIX Packaging Tool has now been released and made it into the Store. Windows 10 Insiders both Slow and Fast Ring can download the package from the store and see what the future of packaging looks like.

Current limitations

The MSIX packaging tool is still in preview and therefore not fully functional below are a few known issues and limitation:

• MSI Packages won't install properly due an Argument issue in Targetdir


• It will be possible to use a different (virtual) machine for Packaging, but at the moment packaging is currently only possible on the (virtual) machine you're running the tool on.


• Customization possibilities are limited


• Singing a MSIX package will not work out of the box

Shopping List

The prerequisites for the MSIX packaging machine are similar to an App-V Sequencing machine:

• Virtual Machine


• 2 Cores and GB of Memory or more


• >60GB Disk Space


• Ability to create Checkpoints


• Internet Connectivity (preferable)

Preparing the Virtual Machine

3. Download the MSIX Packaging Toolkit: https://www.microsoft.com/store/r/9N5LW3JBCXKF


4. Verify it starts properly


5. Shutdown the VM and create a Checkpoint
