Get-AppvClientPackage and Mount-AppVClientPackage fail during Task Sequence RRS feed

  • Question

  • Hi folks, We are attempting to pre-cache and pre-mount our app-v 5.1 applications on clients during a task sequence. Randomly, it fails with the error "AppVStreamingUX.exe - Application Error - The exception unknown software exception (0x0434352) occurred in the application at location 0x000007FFF4AB99E08." Seems to happen randomly on different packages.

    Using SCCM CB 1702, Windows 10 x64 Ent 1703, App-V 5.1 (built-in client).

    Any ideas?

  • Hi Kevin,

    We also faced the same issue in our environment because the task Sequence cache gets removed from the machine as soon as the installation gets completed. We mounted the package as a last step in Task Sequence and till then the cache was gone from the machine for mounting.


    1. Use the single liner

    Add-AppVClientPackage {PkgName} | Publish-AppvClientPackage -Global | Mount-App-VClientPackage

    2. Copy the package first to some temporary location (like C:\Windows\temp) on the machine with the installation script and then install the package from there.

    3. Integrate the Virtual application as an application model since it automatically mounts it during installation.
