BlockExecution causing blocked window spam at end of installation.

Topics: Archive - Deployment Scripts
Apr 1, 2015 at 11:06 PM
I just started using the toolkit yesterday. I have read through the documentation and have been testing some installers. I am having an issue I am trying to get to the bottom of when using -BlockExecution

When the installer is almost finished, the user gets spammed with anywhere from 2-10 blocked execution windows. I am currently removing different blocked exes to see if I can narrow down which one is causing it. I am wondering if it might be Internet Explorer being triggered via Java Web extension being added via WEB_JAVA=1. I have not tried removing that one yet.

Here is the current script I am executing.
    If ($deploymentType -ine 'Uninstall') {
        [string]$installPhase = 'Pre-Installation'
        ## Show Welcome Message, close Internet Explorer if required, allow up to 3 deferrals, verify there is enough disk space to complete the install, and persist the prompt
        Show-InstallationWelcome -CloseApps 'iexplore,javaw,chrome,firefox' -ForceCloseAppsCountdown 300 -AllowDefer -AllowDeferCloseApps -DeferTimes 3 -CheckDiskSpace -PersistPrompt -BlockExecution
        ## Show Progress Message (with the default message)
        Show-InstallationProgress "Installing Java 8 Update 40. Please wait..."
        ## <Perform Pre-Installation tasks here>
        New-Folder -Path "$envProgramData\Oracle\Java" -ContinueOnError $true
        Copy-File -Path "$dirSupportFiles\java.settings.cfg" -Destination "$envProgramData\Oracle\Java\java.settings.cfg" -ContinueOnError $true

        ##* INSTALLATION 
        [string]$installPhase = 'Installation'
        ## <Perform Installation tasks here>


        [string]$installPhase = 'Post-Installation'
        ## <Perform Post-Installation tasks here>
        # Unblock AppExecution

I thought it might have been caused by my uninstall strings, but I added Unblock-AppExecution to the Post-Install portion and it did not change anything.

Anyone encountered this and know what might be going on? I will continue to try to figure out which one is causing the windows and post an update.

Currently I have not looked into all of the different methods you can deploy the toolkit. At the moment each revision takes a few minutes to get set up as I am zipping it all up and having a software distribution deploy it to a test device.

It looks like it is being caused by javaw. Is there anyway to avoid this? I need to have the execution of it blocked, but also don't want the spam windows triggered at the end of the installation.

You can find the path in the registry where the javaw app is blocked and get rid of the path to the script file that gets launched instead of the app. That will stop messages from appearing.

You can also do something with mutexes if you wanted but you'd have to figure that out:

I updated the latest 3.6.1 beta found under the "Source Code" section of the site to implement the mutex I mentioned above. The blocked app message dialog behavior has been improved so that only one message window can be shown at a time. This will prevent multiple message windows from showing up. However, if you don't want any message windows showing up, then you will have to modify that directly for the app by looking at the appropriate key under: HKLM:SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options
