How to uninstall with msiexec using product id guid

You can find the product code by perusing the registry from this base key: HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionUninstall . Press F3 and search for your product name. (If it’s a 32-bit installer on a 64-bit machine, it might be under HKEY_LOCAL_MACHINESOFTWAREWow6432NodeMicrosoftWindowsCurrentVersionUninstall instead).

Finally, you can find the product code also by using PowerShell:

get-wmiobject Win32_Product | Format-Table IdentifyingNumber, Name

when you found the Guid ID you can use msiexec to uninstall the application

msiexec /x {A4BFF20C-A21E-4720-88E5-79D5A5AEB2E8}
