Add custom scripts in AppxManifest.xml file using App-V 5.1 Sequencer

Image
In the Package editor under advanced tab, you can see the Manifest file tab which has been introduced in App-V 5.1. This doesn't exist in earlier versions of App-V. Using this tab, you can export or import the AppxManifest.xml file. Earlier if we want to do any custom changes we have to edit the deploymentconfig or userconfig.xml file(for adding scripts, editing FTA's etc). App-V 5.1 provides advanced way to edit those changes within the AppxManifest.xml. To do so, click on export as highlighted below in the Manifest file tab. This will export the AppxManifest.xml file to the local machine. choose the destination and click on save. Open the exported AppxManifest.xml using AppVManifestEditor.

Decrypting how Microsoft Teams new MSI works

Image
Microsoft has released a windows Installer MSI for Microsoft Teams for deployment through SCCM.You can download it here As per Microsoft Statement: "The Teams MSI will place an installer in Program Files. Whenever a user signs into a new Windows User Profile, the installer will be launched and a copy of Teams application will be installed in that user's appdata folder. If a user already has the Teams app installed in the appdata folder, the MSI installer will skip the process for that user." NOTE: Don't change the install location as it will break the process. In this blog, I will explain how this happens by opening MSI using Installshield. 1. To Install Microsoft Teams, it first requires .net 4.5 or later to be installed in the machine. This check happens using Launch condition which also does a system search for .net registry to be present in the machine. 2. The MSI has only one file which is Teams.exe that gets installed to [ProgramFilesFolder]Teams Installer locat...
