application

Question: Even though when application is closed and no process or child process is running behind, unpublishing the package still shows application is in use and creates a Pending Task entry in the registry key. What is the reason? why it fails? Answer: This issue is happening because of the Dynamic Virtualization (Just In Time virtualization) provided by the App-V 5.0 SP2 and higher.  There are some applications like office, visio etc which has shell integration's that tightly integrates with the Explorer and Internet Explorer by default and are processed to use the virtual components. This is to enable support for enhanced shell extensions like context menu, drag and drop handler, drop target handler,data object handler,property sheet handler,infotip handler,column handler and preview handler. Closing the running application, Internet explorer and trying to unpublish still shows "App in use" error.Even if we try to run the Stop-AppvClientPackage command in an elevat...

Recently I have seen many queries in Technet and other groups about whether there is an App-V 5.1 client GUI available or they couldn't see the client GUI after installing App-V 5.1 client. So let me clear this confusion first. Microsoft doesn't provide a client GUI for App-V 5.1.Though it has stated in the below links that there is an UI available for App-V 5.1, it doesn't provide any link to download nor has a separate shortcut which I confirmed by opening the MSI and had a look for any client UI shortcut. https://technet.microsoft.com/en-us/library/mt346490%28v=vs.85%29.aspx https://technet.microsoft.com/en-us/library/mt346576%28v=vs.85%29.aspx (Have posted in Technet about this false informations. check HERE .Hope MS will look into it.)  We already know that it stopped providing GUI from App-V 5.0 SP2. Beginning App-V 5.0 SP2, Microsoft started providing a separate client GUI which can be downloaded from the below link. https://www.microsoft.com/en-gb/download/details.a...

After upgrading from App-V 5.0 Sp2 or App-V SP3 to App-V 5.1 , Internet explorer starts crashing for no reason. The Application event log shows two possible errors: 1.Faulting module : EMET.DLL 2.Faulting module : NTDLL.DLL This is a known bug with App-V 5.1. Some possible workaround is to either revert back to 5.0 or follow the below steps. Solution: Remove the following lines in the registry and IE 10 / IE 11 will stop crashing. HKEY_LOCAL_MACHINE / SOFTWARE / Microsoft / AppV / Client /Virtualization ProcessesUSingVirtualComponents Data: %ProgramFiles%\Internet Explorer\iexplorer.exe %ProgramFiles(x86)%\Internet Explorer\iexplorer.exe You can also try removing the App-V 5.0 earlier versions manually and then install App-V 5.1 instead of upgrading to avoid this issue. Though the above said step is just a workaround, it is not a recommended way to bypass this issue. We need to wait for Microsoft to come up with possible fix or service pack soon.
