uninstall using registry uninstall string powershell - arrays

Question

I'm trying to create a powershell script that will uninstall all versions of a program in our studio.
I had a look at the registry and can see that we have 3 strings of the program installed in our studio computers
{D4BE10F2-3E2D-4120-863A-765623D53264}
{77067FD9-800C-48B4-803D-569642ADABC5}
{1DB1AEB7-EDBD-4BB1-87DB-26C72576DA42}
I created a test script:
msiexec.exe /x{D4BE10F2-3E2D-4120-863A-765623D53264} /q
and used it on a machine, this worked and that version of the program was uninstalled.
I want to create a script that cycle all 3 strings and Success on the correct one, as I don't know what machine has what version without doing a scan.
so I created a `powershell script:
foreach ($guid in '{D4BE10F2-3E2D-4120-863A-765623D53264}',
'{77067FD9-800C-48B4-803D-569642ADABC5}',
'{1DB1AEB7-EDBD-4BB1-87DB-26C72576DA42}') {
$exe = 'C:\Windows\System32\msiexec.exe'
$ps = Start-Process -PassThru -Wait $exe "/x /q"
if ($ps.ExitCode -eq 0) { "Success"; exit 0 }
}
Write-Warning "Uninstallation failed."
exit $ps.ExitCode
This is not working for me as it keeps returning with Uninstallation failed, I'm not sure whats going on.
Any advice?

This will work even if there are all three versions installed:
foreach ($guid in '{D4BE10F2-3E2D-4120-863A-765623D53264}',
'{77067FD9-800C-48B4-803D-569642ADABC5}',
'{1DB1AEB7-EDBD-4BB1-87DB-26C72576DA42}') {
$exe = 'C:\Windows\System32\msiexec.exe'
$ps = Start-Process $exe -ArgumentList "/x$guid /q" -PassThru -Wait
if ($ps.ExitCode -eq 0) {
Write-Host "$($guid): Success"
} else {
Write-Host "$($guid): Failed"
}
}
