Thanks John, was able to install the MSIX packaging driver once we fix there insider issue, however now the problem is while signing which was highlighted by Anonymous earlier here. Do we have any solution for this?
If I try to sign the sign the MSIX Package with my Self Signed PFX it fails: [7/26/2018 12:46:08 PM] [Debug] About to start process [7/26/2018 12:46:08 PM] [Debug] - File name: signtool.exe [7/26/2018 12:46:08 PM] [Debug] - Arguments: sign /a /v /fd SHA256 /f "C:\Users\hcadmin\Desktop\MSIX\Sumatra.pfx" "C:\Users\hcadmin\Desktop\MSIX\SumatraPDF-3.1.2-install.msix" [7/26/2018 12:46:08 PM] [Error] signtool.exe failed, exit code = 1 [7/26/2018 12:46:08 PM] [Error] Error occured: Microsoft.Packaging.SDKUtils.ProcessRunner.ProcessRunnerException: Process signtool.exe failed with exit code 1. at Microsoft.Packaging.SDKUtils.ProcessRunner.ProcessRunnerBase.ValidateExitCode() at MsixGenerator.MsixPackageGenerator.RunSignTool(String packagePath, String certificatePath) at MsixGenerator.MsixPackageGenerator.FinalizePackage(CancellationTokenSource cancellationTokenSource) at MsixPackagingTool.ViewModel.Common.ViewModelBase.CreatePackage(Object sender, DoWorkEventArgs doWorkEventArgs) at System.ComponentModel.BackgroundWorker.OnDoWork(DoWorkEventArgs e) at System.ComponentModel.BackgroundWorker.WorkerThreadStart(Object argument)
