Verify if a program is installed

[simonaferrara]

 Hi all,

someone know if there could be a method to check if a program is installed?

During a test, I'm installing an msi, and I would like to verify if the program belongs to the list of the installed programs within the operating system (that is: the programs that I see within "Control Panel -> Programs and Features").

Thanks!

Hi,

After the install we could run a process method (https://support.smartbear.com/testcomplete/docs/reference/test-objects/members/sys/process-method-sy...)  It simply searches for it among all processes that currently exist in the system.

So I would add this as a validation after the install step 

Best,
Matt

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
