Im new to this tool and I have to say I love it. Makes deployment so much easier.

Is there a way to block executions silently?
Im currently using this tool for a Java deployment and we have a Printing solution that is constantly trying to restart javaw.exe so the users will in some cases get promted with about 5-10 windows from the BlockExecution function during install. A bit annoying and it will make our users confused and start calling our helpdesk, so in this case I would like to do it silently.
Is it possible?
I have searched but cant find anything.

You can simply call the Block-AppExecution function directly to silently block the application.

Call it directly? Care to elaborate on that?

Normally you block applications by specifying them when using the welcome prompt function. The welcome prompt function basically calls Block-AppExecution to do the blocking. If you don't want the prompt, then just call Block-AppExecution and don't use the prompt to do the blocking. The function has an example which shows how to use it.

Create blank empty vbs "AppDeployToolkit_BlockAppExecutionMessage_Blank.vbs" and store it on AppDeployToolkit folder
Create new Function on AppDeployToolkitExtensions.ps1
Function HiddeBlockMessage {
    Hide Block message
    Modify registry key pointing to blank vbs script
    Param (
    Begin {
        ## Get the name of this function and write header
        [string]${CmdletName} = $PSCmdlet.MyInvocation.MyCommand.Name
        Write-FunctionHeaderOrFooter -CmdletName ${CmdletName} -CmdletBoundParameters $PSBoundParameters -Header
    Process {
        Try {
                [string]$regKeyAppEx= 'HKLM:SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options'
                [psobject[]]$unblockPName = Get-ChildItem -Path $regKeyAppEx -Recurse -ErrorAction 'SilentlyContinue' | ForEach-Object { Get-ItemProperty -LiteralPath $_.PSPath } | Where-Object { $_.Debugger -like '*AppDeployToolkit_BlockAppExecutionMessage*' }
                ForEach ($unblockP in $unblockPName) 
                $unblockP | Set-ItemProperty -Name Debugger -Value 'wscript.exe "C:\Users\Public\aG Deployment Kit\AppDeployToolkit_BlockAppExecutionMessage_Blank.vbs"'
        Catch {
            Write-Log -Message "<error message>. `n$(Resolve-Error)" -Severity 3 -Source ${CmdletName}
    End {
        Write-FunctionHeaderOrFooter -CmdletName ${CmdletName} -Footer
Call function HiddeBlockMessage on Deploy-Application.ps1 After InstallationWelcome
Show-InstallationWelcome -CloseApps ......

I have tried using Block-AppExecution -ProcessName 'javaw,iexplore,chrome,firefox,safari' after Show-InstallationWelcome, no luck, I get the Close App promt.
I have also tried using it in pre installation task but it doesnt work at all, no block.
