Still kinda new to PoSH scripting so if I made a stupid mistake lemme know. I've been piecing and building this all afternoon to test if App installed, if not installed run installer but I didn't want it stuck in an eternal look so I figured I would have it try install once, and also catch if already installed remove/re-install. But this block is stuck where the arrow points. $App_Test_Count is set to 1 after running code every time and it won't increment, Why?

​

Function App_Test(){
    If(Test-Path $App_Loc){
        $Global:Inst_Ver_App = (Get-Command $App_Loc).FileVersionInfo.FileVersion
        [Bool]$Global:App_Test = $True
        # Insert Code here for Logging
    } ElseIf (!(Test-Path $App_Loc)){
        $App_Test_Count = 0
        While($App_Test_Count -le 2){

IF($App_Test_Count = 1){

            IF($App_Test_Count -eq 1){
                Write-Host "App will be Removed and Re-Installed Now"
                # Insert Code here to Un-Install App
                # Insert Code here to Install App
                # Insert Code here for Logging
                $App_Test_Count  

} ElseIf($App_Test_Count = 0){

            } ElseIf($App_Test_Count -eq 0){
                Write-Host "App will be Installed Now"
                # Insert Code here to Install App
                # Insert Code here for Logging
                $App_Test_Count  
            }
        }   
    }
}

Edited to show corrected and working script.
