    Hi, when mandatory profile used, profile sometimes still not being unloaded during logoff. Tested with 5.1.

    Hi, if mandatory profile used, profile is not unloaded properly during logoff. Tested with 5.1 and even with this new hotfix. Profile is hanged in ProfileList registry key. When the key is deleted, profile will finish unloading and cached profile is removed.

  3. Sizzl says:

    I can also confirm the same behaviour that Jozef has mentioned; however AppVClient.exe is correctly (eventually) releasing the lock on the VFS folder – just likely that it’s not doing it quick enough for the profile service to clean up the folder structure
    / ProfileList registry.

    This isn’t the end of the world for our setup, as users can successfully log back in without it creating a temporary profile (as was the behaviour before 5.1 HF2). So for us, it’s "good enough".

    Hi All, We've been experiencing issues on multiple devices running Win 8.1 and 10 with the explorer.exe process preventing from running. This results in a black screen after logon, only salvageable by firing up task manager and killing the appvclient service.
    On further investigation: removing C:windowsexplorer.exe from the HKLMSoftwareMicrosoftAppVClientVirtualizationEnableDynamicVirtualization key prevents the issue from reoccurring. Has anyone experienced this and what affect does removing the explorer.exe
    from that reg key have on appv functionality?

    Still having issues with the profile being locked on log off, it is much better but it still causes us issues. Will log a call with Microsoft now. Definitely App-V as if I disable the App-V service then the profiles load and unload perfectly. 🙁

      If it helps anyone our profile unload issues was resolved with hot fix

      Microsoft refunded our case after finding this for us.

    I too still have the issue with the %USERPROFILE%\AppData\Local\Microsoft\Appv\Client\VFS folder being locked by the App-V client on logoff after applying this hotfix.

    Having an issue, just downloaded 5.1 HF2 today to troubleshoot an issue but it won’t install, says base product is not installed and log shows;

    [12BC:116C][2016-07-18T10:21:13]i105: Detected package: CoreX86Patch target: {B2A6CCDE-5E94-43D8-B47E-A455CEF33C4B}, state: Absent

    But IS installed, both installed and functioning (here’s the registered MSI info);


    5.1 was installed on Windows 7 via WDS deployment, it’s not an upgrade and works fine, been in our environment for many years. Tried to extract MSI from EXE to be sure it’s not an MSI-over-EXE problem and exe launches endless processes but never does anything, seems to be stuck in a loop when run via;

    AppV5.1RTM_Client_KB3139245.exe /Layout /LayoutDir=”C:\Sequences”

    Error log indicates;

    [2230:2234][2016-07-18T10:17:25]e000: Error 0x800700ce: Failed to launch parent process with unelevate disabled: C:\Sequences\App-V 5.1 HF2\AppV5.1RTM_Client_KB3139245.exe

      Never mind, exe (patch) can be extracted on Windows 10 machines and resultant MSO installed just fine…
