How to determine the type of installation?

I am trying to uninstall apps silently. So how can I determine the type of installer (ex: Inno setup, NSIS, InstallShield, MSI, etc.) in windows? Can anyone help me with this?

If you look into the SilentInstaller source, you will see PEiDs to look at the executor resources. A simple method is to find keywords like Inno Setup, Install Shield, ... in executabile. Hard method - every installer has a signature, like a virus, I think it can be figured out, but it takes too long. Hard method - find the calculation of the offset of the keywords of each installer.
