Run command If fails then run the other one if success then end

Question

I'm trying to find a way to uninstall maya2019 from all studio workstation. We have 3 versions of maya2019 with different uninstall commands:

"C:\Program Files\Autodesk\Maya2019\Setup\Setup.exe" /P {D4BE10F2-3E2D-4120-863A-765623D53264} /M MAYA /LANG en-us /q

"C:\Program Files\Autodesk\Maya2019\Setup\Setup.exe" /P {77067FD9-800C-48B4-803D-569642ADABC5} /M MAYA /LANG en-us /q

"C:\Program Files\Autodesk\Maya2019\Setup\Setup.exe" /P {1DB1AEB7-EDBD-4BB1-87DB-26C72576DA42} /M MAYA /LANG en-us /q

I need to make a script that runs the commands, if one fails then it runs the the next one down, if it succeed the it exits with complete and stops.

Right now I have this:

if "C:\Program Files\Autodesk\Maya2019\Setup\Setup.exe" /P {D4BE10F2-3E2D-4120-863A-765623D53264} /M MAYA /LANG en-us /q; then
    echo success && exit
else
if "C:\Program Files\Autodesk\Maya2019\Setup\Setup.exe" /P {77067FD9-800C-48B4-803D-569642ADABC5} /M MAYA /LANG en-us /q; then
    echo success && exit
else
if "C:\Program Files\Autodesk\Maya2019\Setup\Setup.exe" /P {77067FD9-800C-48B4-803D-569642ADABC5} /M MAYA /LANG en-us /q; then
    echo success && exit

but I'm not sure if I'm going in the right direction?

Thanks for your help

Answer 1

As suggested by Theo in the comments on the question, a more efficient solution would be to query the registry at HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall for uninstallation command lines based on the GUIDs in your commands.

^{This answer provides pointers as to how to do that.}

If that is not an option, here'a PowerShell solution:

foreach ($guid in '{D4BE10F2-3E2D-4120-863A-765623D53264}', 
                  '{77067FD9-800C-48B4-803D-569642ADABC5}', 
                  '{1DB1AEB7-EDBD-4BB1-87DB-26C72576DA42}') {

  $exe = 'C:\Program Files\Autodesk\Maya2019\Setup\Setup.exe'

  $ps = Start-Process -PassThru -Wait $exe "/P $guid /M MAYA /LANG en-us /q"

  if ($ps.ExitCode -eq 0) { "Success"; exit 0 }

}

Write-Warning "Uninstallation failed."
exit $ps.ExitCode

Start-Process -PassThru -Wait starts the installer process, waits for its termination, and then returns a System.Diagnostics.Process instance representing the terminated process, whose exit code (.ExitCode) can then be examined. An exit code of 0 signals success, any other value failure.
