    Hi, 

     

    anyone have got other ideas? 

     

    I can check the processes related to the application (as mattb explain) but this check is currently not enough, I would like to find a way to check if the application appears within the "Program and Feature" list.

     

    Thanks

    Simona

      Hi Simona, 

       

      This is also an option using powershell script, but check the feasibility from your end

       

      ****************** Test Complete Code***************************************

      function CheckProgramInstalled()
      {
      var WSH = Sys["OleObject"]("WScript.Shell");
      var objExec = WSH["Exec"]("powershell -file C:\\****\\PowerscriptName.ps1");
      objExec ["StdIn"]["Close"]();
      var strOutput = objExec ["StdOut"]["ReadAll"]();
      Log["Message"](strOutput);
      }

      ****************** Test Complete Code***************************************

       

      in the above code power script(PS1 file - C:\\****\\PowerscriptName.ps1) is being used, you could create that file with below code using node pad and save as .ps1 extension or using powershell ise or VS CODE

       

      $software = "PROGRAM  NAME THAT YOU ARE SEARCHING";
      $installed = (Get-ItemProperty HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall\* | Where { $_.DisplayName -eq $software }) -ne $null

      If(-Not $installed) {
      Write-Host "'$software' is not installed";
      } else {
      Write-Host "'$software' is installed."
      }

       

      It works if machine is 64 bit

       

      Else you can check using below in 2nd line of powershell script - I have not tried this

      HKLM:\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstal  in 2nd line of powershell script
